That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (15 plus or minus the square root of -3) divided by 2
x = 7.5 + 0.8660254i
x = -0.8660254i
where i is the square root of negative one.
57 = 3*19
3 x 19 = 57
3 x 19 = 57
3 x 19 = 57
49 is not prime - its prime factorization is 72. 57 is not prime - its prime factorization is 19 x 3.
57 = 3 * 19It is: 3 and 19
57 = 31 x 191
3•19
57 + 57 + 38 + 38 = 190
Prime factorization of 57 = 3 x 19Prime factorization of 51 = 3 x 17It is clear that only 3 is common in the factorization of 57 and 51.So, GCF(57, 51) = 3.GCF is 3.51 = 3 x 1757 = 3 x 19
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.
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
