49 is not prime - its prime factorization is 72. 57 is not prime - its prime factorization is 19 x 3.
57 = 3*19
3 x 19 = 57
Prime factorization is the finding which prime number multiply to get to make the original number. 57: 1, 3, 19, 57 Prime Factors: 3, 19 3 x 19 = 57
3•19
3 x 19 = 57
57 = 3 * 19It is: 3 and 19
57 = 31 x 191
Prime Factorization of 57The prime factorization of 57 is:3 X 19Both factors are prime, so the prime factorization of 57 is 3 X 19.
Prime factorization of 343 = 7 x 7 x 7 Prime factorization of 57 = 3 x 19 It is clear that no prime number is common in the prime factorizations. Therefore, GCF of 343 & 57 is 1.
It is 31 and 191
The greatest common factor of 38 and 57 is 19. The prime factorization of 38 is 2*19 The prime factorization of 57 is 3*19 So the GCF is 19.
