85 has four factors.
No because they are both composite numbers having more than two factors whereas prime numbers have only two factors
40 and 50 are both composite numbers because they have more than two factors
6, 10, 15, 25, 30, 50, 75, 150
The common factors of 15 and 50 are 1 and 5
The common factors of 50 and 15 are 1 & 5.
2 and 5. The factors of 50 (i.e., the whole numbers that evenly divide into 50) are 2, 5, 10, 25, and 50. Of these numbers, only 2 and 5 are prime numbers.
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors are 1 and 5. Therefore, the greatest common factor is 5.
1The factors of 49: 1 * 7 * 7.The factors of 50: 1 * 5 * 5 * 2.The only factor that both numbers have in common is 1.
There are 15 prime numbers up to 50.
Prime numbers have only two factors.
The prime numbers (factors) of 50 are: 2 and 5
