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
To find the pairs of whole numbers that multiply to equal 40, we can identify the factor pairs of 40. The pairs are (1, 40), (2, 20), (4, 10), and (5, 8). Including the reverse pairs, there are a total of 8 pairs: (1, 40), (40, 1), (2, 20), (20, 2), (4, 10), (10, 4), (5, 8), and (8, 5). Thus, there are 8 pairs of whole numbers that equal 40.
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.
Between 65 and 105, there are three twin prime pairs: (71, 73), (101, 103). Twin primes are pairs of prime numbers that differ by two, and these pairs are the only ones within the specified range.
Factors go in pairs; prime factors are listed least to greatest. 2, 3 and 11
