The greatest number that both 42 and 56 are divisible by is their greatest common divisor (GCD). To find the GCD, we can use the prime factorization method: 42 can be factored into (2 \times 3 \times 7) and 56 into (2^3 \times 7). The common factors are (2) and (7), and the GCD is (2 \times 7 = 14). Therefore, the greatest number that both 42 and 56 are divisible by is 14.
42 and 84 both qualify
The number that goes into both 42 and 12 is their greatest common divisor (GCD). The GCD of 42 and 12 is 6, as 6 is the largest number that can divide both without leaving a remainder. Therefore, 6 is the number that goes into both 42 and 12.
Yes, both.
42
42 and 49 are both divisible by 7. 42/49= 6/7
The greatest number that both 42 and 56 are divisible by is their greatest common divisor (GCD). To find the GCD, we can list the factors of each number: the factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42; the factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. The largest common factor is 14, so the GCD of 42 and 56 is 14.
42 and 84 both qualify
Numbers that are divisible by both 6 and 7 must be divisible by the least common multiple of 6 and 7, which is 42. Therefore, the numbers divisible by both 6 and 7 are multiples of 42. This includes numbers like 42, 84, 126, and so on.
21. GCF means what is the greatest number that goes into both, and 21*2=42.
The number that goes into both 42 and 12 is their greatest common divisor (GCD). The GCD of 42 and 12 is 6, as 6 is the largest number that can divide both without leaving a remainder. Therefore, 6 is the number that goes into both 42 and 12.
The difference between a number and its reverse must be divisible by 9. 42 is NOT divisible by 9. There is, therefore, no such number.
Both are divisible by 6.
Yes, both.
42 is divisible by 2 (and other factors) so it is a composite number
42
42 and 49 are both divisible by 7. 42/49= 6/7
The list is infinite. Here are some of them: 12, 18, 24, 30, 36, 42.
