2 and 5
The GCF is 10.
13 is a prime number. Its only factors are ' 1 ' and itself.So the only factor it shares with 50 is ' 1 '.
20 and 112 25 and 50 20, 50, 60 and 70
5 is the only prime number in which 5 is a factor.
4 is a prime factor of 20 whereas it isn't a factor of 50.
The GCF of 15, 24, and 72 is 3. There is no GCF for 63, 20, and 50. This makes it relatively prime.
The common factors of 20 and 50 are: 1, 2, 5, 10.
Same as the greatest common factor of 50 and 20 - where 20 is the remainder of the division of 70 by 50.
The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors of 20 and 50 are 1, 2, 5, and 10. Therefore, the least common factor (the smallest common factor) is 1.
It is 1 because 7 is a prime number and is not a factor of 50
21 is not a prime factor, it is 3 x 7
The GCF of 20 and 50 is 10. 50-(1,2,5,10,25,50) 20-(1,2,4,5,10,20)
The only common factor of 15, 18, 20, and 50 is 1.
The greatest common factor of a prime and a composite number is 1 if the composite number is not divisible by the prime number. 37 is a prime number and 50 is a composite number. Also, 50 is not divisible by 37 therefore GCF = 1.
20:1,2,4,5,10,20 50:1,2,5,10,25,50 GCF:10
The greatest common factor of the numbers 20, 35 and 50 is 5.
