No, they're both divisible by three
No.
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime
75,112
No. They are both multiples of 3.
What 4 numbers times together makes 56
They are 3 and 7
3 x 7 x 7
No because they both have more than two factors
To find the greatest common factor of two numbers, you first need to break those numbers down into their prime factors. For 105 and 147 this is: 105 = 3x5x7 147 = 3x7x7 The next step is to identify any common prime factors. In this case, both numbers have a 3 as a prime factor, and a 7 as a prime factor. Multiply these together to get the GCF: 3x7 = 21 Thus the greatest common factor of 105 and 147 is 21.
No, it is not a prime. 147=3*7*7.
147=3x7x7
147 is a composite number. 147/3= 49
