2 x 5 x 7 = 70
10, 20, 30, 40, 50, 60, 70, 80, 90
The GCF of 15 and 70 is 5.The prime factorization of 15 is 3*5.The prime factorization of 70 is 2*5*7.The only, and greatest, common factor is 5.The GCF is 5.
Looks like 70, 490 = 7 x 70, 630 = 9 x 70 and 7 and 9 are co-prime.
No prime power exists since there are no duplicate prime numbers in the prime factorization.
Method of prime factorization is one of the best methods to find L.C.M. Prime factorization of 81 = 3x3x3x3 Prime factorization of 70 = 2x5x7 It is clear that nothing is common in Prime Factorization of both numbers. Also, L.C.M. = Product of common numbers x Product of uncommon factors So, L.C.M. of 81 and 70 = Product of 81 and 70(Because nothing is common in 71 and 80) = 81 x 70 = 5670
Greatest Prime Factor of 70The prime factorization of 70 is 2 X 5 X 7, so the greatest prime factor in the prime factorization of 70 is 7.
The prime factorization of 70 is 2 x 5 x 7.
73 is a prime number but 70 is not. 70 is a multiple of: 2, 5, 7, 10, 14 and 35 (as well as 1 and 70); the prime factorization of 70 is 2 × 5 × 7.
As a product of its prime factors: 2*5*7 = 70 Note that at least two or more numbers are needed to find their HCF
