7 and 5 are prime numbers, but 3*2=6
5, 7, and 3 go into 105.
7 8 and 9 go into evenly in the multiples of 504.Multiples of 504 are 504, 1008, 1512, ...prime factorization of:7 =.... 78 = .........2 x 2 x 29 = .........................3 x 3=================LCM= 7 x 2 x 2 x 2 x 3 x 3 = 504
It is: 3*5*7 = 105
prime factorizing, 63 = 3*3*7 and 28 = 2*2*7, so the answer is 7.

7 and 5 are prime numbers, but 3*2=6
5, 7, and 3 go into 105.
The number is two.
No, since 7/3 is = to the mixed number 2 1/3 3 - 2 1/3 = 2/3
7 8 and 9 go into evenly in the multiples of 504.Multiples of 504 are 504, 1008, 1512, ...prime factorization of:7 =.... 78 = .........2 x 2 x 29 = .........................3 x 3=================LCM= 7 x 2 x 2 x 2 x 3 x 3 = 504
42. 2*3*7=42.
No 21/3 = 7 21/2 = 10.5 so not a whole number 2 goes into 20 or 22 but not 21
2^3 * 3^2 * 5 * 7
LCM(2, 3, 7) = 42
2 and 7/4 is a mixed number. It can also be written as 3 and 3/4
