One solution is, 31 + (2 x 4) = 31 + 8 = 39 Another is, 42 - (1 x 3) = 42 - 3 = 39
31 37 41.
The factors of 39 are: 1 3 13 39 The prime factors are: 3 and 13
39% of 42 = 42*39/100 = 16.38
37 + 5 31 + 11
No, they are both composite.
One solution is, 31 + (2 x 4) = 31 + 8 = 39 Another is, 42 - (1 x 3) = 42 - 3 = 39
It is: 21*31*71 = 42
No they have common factor of 3
no answer 31 is a prime number so no reduction possible
31 37 41.
