product
21 = 3 x 7
I think most people have a hard time answering this question. As do I. The product of a prime factor will always be consecutive Ex.1: 3*7=21 factors of 21- 1, 3, 7, and 21. Hope it helped....LiveaLifeofLove
no. factors are numbers which you multiply to get that product. You can't multiply 75 with any other number to get 96 asd its product. Neither can you do it with the number 21.
-21 has four factor pairs. (21,-1)(-21,1)(7,-3)(-7,3) None of them have a sum of -8.
21 or 35
Factor tree:126|63 and 2|21 and 32 x 3 x 21 = 126
A factor multiplies with another factor to create a product.
21 is the largest factor of 21
21 and -10 are co-prime. They only have the factor "1" in common. If you mean what numbers add to -10, whose product is 21, that would be -3 and -7.
The greatest factor of 21 and 16 is 21, which is a factor of 21 but not of 16.
Because 21 is a factor of 63. 21 is the greatest factor of 21. A larger number doesn't exist.
Aside from itself (21), the highest integer factor of 21 is 7.
