The (LCM) Least Common Multiple of 7 and 3 is 21 because that is the LEAST number that both 3 and 7 go into.
8 x 7 = 56, 7 x 3 = 21, so 7
It is: 4 and 3/7 as a mixed number
1, 3, 7, 9, 21, 63
at up the digits in the number and if the sum is a multiple of three then it means that 3 can go into the number.eg. the number 27... 2+7=9 and 9 is a multiple of three so 3 can go into 273*9 =27
5 is.
2
37/7
5, 7, and 3 go into 105.
It is: 35
There are 4 items to choose from, and 3 of them, so the answer is 43 = 64.
It is: 3*5*7 = 105
