First, you have to find the number that is a multiple of 7. That number is 126 because 7 x 18 = 126. Then, you need to find the prime factorization. You can do that by starting with any factor pair of 126 and keep factoring the composite factors until all factors are prime. 126: 2 x 61 Since 2 and 61 are prime, that is the prime factorization of 126.
If you mean the product of its prime factors then it is: 2*3*3*7 = 126
6=1x2x3 7=1x7 9=1x3x3 LCM is the prime factors that were the MOST in any one number. 1x2x3x3x7=126
As a product of its prime factors: 2*3*3*7 = 126 or as 2*32*7 = 126
The prime factors of 105 are 3, 5, and 7.The prime factors of 126 are 2, 3, 3, and 7.Therefore the prime factors that 105 and 126 have in common are 3, and 7.
