The only common factor of 4 and 5 is 1. 4 and 5 are common factors of 20 and 40.
1,2,4
The only factor that all of these numbers share is 1 since 3 and 5 are prime. So 1 is the gcf of this set of numbers.
4
Numbers with 3 or 5 factors are called square numbers.
5 is a prime number having 1 and 5 as its only factors. It makes no difference to the factors of 5 if the digit 5 is in composite numbers.
20
The GCF is: 1
No. 3 and 4 are not factors of 10.
Yes because 3, 4 and 5 complies with Pythagoras' theorem for a right angle triangle.
That could either be "What numbers have 5 factors" or "What numbers have 2 and 5 as factors." Prime numbers to the fourth power, like 16 and 81, have 5 factors. Any multiple of 10 has 2 and 5 as a factor.
4 factors to [2 2] 6 factors to [2 3] 10 factors to [2 5] The most 2s in a number is 2, the most 3s is 1, and the most 5s is 1. 2*2*3*5=120
