It is: 2*3*7 = 42
Three ways to factor 42 are factor trees, fireworks and rainbows.
No. 42 is composite and therefore cannot be a prime factor.
The largest prime factor of 42 is 7
42 21,2 7,3,2
A Factor tree looks like this:... 42... / . \..2 ...21....... / . \.......3 . 7So the prime factors of 42 are 2 x 3 x 7
The product of the prime factors of 42 is 42.
1, 2, 3, 7 are the prime factors of 42.
I suppose there are six ways to list them, but generally we stick to least to greatest.
3 2 x 3 x 7 = 42 Since 42 is a multiple of 3, it is automatically the LCM of the pair.
Start by breaking 42 into any of its factors. I like to start by using factors I know are prime. In this case, I'll begin with 2 and 21. 42 (This is the number we began with) 2*21=42 (2 is always an easy prime factor for any even number) 2*3*7=42 (21=3*7. Both 3 and 7 are prime, so were done.)
The only common factor of 13 and 42 is 1, since 13 is prime and 42 is not a multiple of 13.
2 and 7 are prime numbers less than 10 that are factors of 42 and 70.
