420 has four prime factors. Prime factors don't usually travel in pairs.
There are 490 coprime pairs and I have neither the time nor inclination to list them all.
The factors of 40 are: 1 2 4 5 8 10 20 40 The prime factors are: 2 x 2 x 2 x 5 Answer: 4
The prime factorization of 100 is 2x2x5x5. There are no pairs of prime factorization with a difference of two in the number 100.
It can be. 40 is relatively prime to 41. 40 is not relatively prime to 54.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.
Factors go in pairs; prime factors are listed least to greatest. 2, 3 and 11
The ones that are relatively prime, or co-prime.
Yes.
