2 and 3
2 and 3 are the only common prime factors
The prime factors of 84 are: 2,3,7The prime factors of 360 are: 2,3,5
The prime factors of 84 are: 2, 3 and 7.
The prime factors are: 2,3,7They are: 2, 3 and 7The prime factors of 84 are: 2,3,7The prime factors of 84 are: 2,3,7
To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 21 are 3 and 7. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 7. Therefore, the lowest common multiple is 21 x 28 ÷ 7 = 84
The prime factors of 84 are 2x2x3x7.
To do this, you first have to break 84 and 108 down into their prime factors: 84 = 2x2x3x7 108 = 2x2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have two 2s and a 3 as prime factors. Multiply these together and you get 12. Therefore the HCF of 84 and 108 is 12.
By prime factoring 84 you get 2x2x7x3. These are all the factors of 84
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 84 are 2, 2, 3, and 7. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
The GCF of 48 and 84 is 12. One way is to list all the factors of both numbers and compare them. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 48 are 2, 2, 2, 2, and 3. The prime factors of 84 are 2, 2, 3, and 7. The prime factors they have in common are 2, 2, and 3, so the greatest common factor is 2 x 2 x 3 = 12
The GCF of 72 and 84 is 12. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors of 84 are 2, 2, 3, and 7. The prime factors in common are 2, 2, and 3, so the greatest common factor is 2 x 2 x 3 = 12.
Prime factorization of each: 84 = 22*3*7 125=53 So, these numbers are relatively prime and GCF=1.
