7 x 8 = 58 When you factor that into prime factors:
7 x 2 x 4
7 x 2 x 2 x 2
you get the four prime numbers that equal 56.
Numbers cannot "make" another number prime. If you are looking for the prime factorization of 56, it is 23 * 7.
add 7, 11, 13, and 23 together multiply 2 x 2 x 2 x 7
53 and 3 are two prime numbers that add up to 56
56 does not have only three prime factors.

Numbers cannot "make" another number prime. If you are looking for the prime factorization of 56, it is 23 * 7.
The prime numbers (factors) of 56 are: 2 and 7
The prime numbers (factors) of 56 are: 2 and 7
3 and 53
add 7, 11, 13, and 23 together multiply 2 x 2 x 2 x 7
To get the gcf of 56 and 48, you have to split the numbers into their prime factors: 56 = 2x2x2x7 48 = 2x2x2x2x3 Next you have to spot any common prime factors. In this case both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 And so the GCF of 56 and 48 is 8.
One number has to be 7, because that is a prime factor of 56. The other two numbers must total 8 and multiply to 8. Can't be done...
7 * 8 = 56 1 * 56 = 56
56=2x2x2x7
7*8 = 56
168
The factors of 56 are... 1,2,4,7,8,14,28, and 56
