1, 61
It is 8.
6 x 7 = 42 (it helps to know the multiplication tables), so the prime factors are 2 x 3 x 7, and the combination is 237
The factors of 37 are 1 and 37. The factors of 81 are 1, 3, 9, 27, and 81. They have only one factor in common - 1. Since the greatest common factor of 37 and 81 is 1, they are relatively prime. You can also look at the prime factors to determine the greatest common factor. 37 is a prime number, so its only prime factor is itself, 37. The prime factors of 81 are 3, 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their greatest common factor is 1.
Prime factors are 3 & 5. You should have no difficulty in calculating the composites, if any...
The factors of 21 are 1, 3, 7, and 21. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors they have in common are 1 and 3, the largest of which is 3, so 3 is the greatest common factor. Or, you can calculate the greatest common factor by looking at the prime factors. The prime factors of 21 are 3 and 7. The prime factors of 36 are 2, 2, 3, and 3. The prime factors they have in common are a single 3, so 3 is the greatest common factor.
As a product of its prime factors: 2*2*2*3*5 = 120
1 & 59... 59 is a prime number !
2 and 17
3 x 3 x 5
Factors go in pairs; prime factors are listed least to greatest. 2, 3 and 11
That just means to put the numbers in numerical order. The prime factorization of 210 from least to greatest is 2 x 3 x 5 x 7
It is 8.
45
2 x 3 x 3 x 5 = 90
Not really. It's traditional to list them least to greatest.
5 - 2 = 3
22*5*11 . Generally you list the prime factors in order from least to greatest.
