Greatest number both 42 and 56 are divisible by?

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.

What is the least common multiple of 2 7 and 8?

To find the least common multiple (LCM) of 2, 7, and 8, we first need to find the prime factorization of each number. The prime factorization of 2 is 2, 7 is already a prime number, and 8 is 2 x 2 x 2. Then, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2^3 x 7 = 56. Therefore, the least common multiple of 2, 7, and 8 is 56.

Is 6 a multiple of 56?

No.To check for divisibility by 6, the number must be divisible by both 2 and 3:To check divisibility by 2: if the number is even (last digit is one of 0, 2, 4, 6, 8) then the number is divisible by 2. Last digit of 56 is 6 which is even so 56 is divisible by 2.To check divisibility by 3: if the sum of the digits is divisible by 3, then so is the original number; the test can be repeated on the sum, so if it is repeated until a single digit remains, the original number is divisible by 3 if this single digit is 3, 6 or 9.For 56: 5 + 6 = 11 → 11: 1 + 1 = 2; 2 is not one of 3, 6 or 9, thus 56 is not divisible by 3.As 56 is not divisible by both 2 and 3, it is not divisible by 6.No.We can ask ourselves what are the multiples of six?6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, and so on.We see that 56 is not in this set of numbers. So it's not a multiple of six. We can also see that each of these numbers can be divided by six. So a quicker way of deciding would be to try to divide 56 by 6. 56/6 = 9-4/6 or 9-2/3. It doesn't divide evenly so again, 56 is not a multiple of 6.no60 = 6 x 1054 = 6 x 9so 56 is not a multiple of 6
