The factors of 3 are 1 and 3.The factors of 4 are 1, 2, and 4.The factors of 5 are 1 and 5.The only common factor of 3, 4, and 5 is 1. The least common factor is 1.
As they do not have any common factors, the least common multiple (LCM) of 4 and 5 is 4*5, that is 20.
The factors of 5 are 1 and 5. The factors of 10 are 1, 2, 5, and 10. The factors of 20 are 1, 2, 4, 5, 10, and 20. The common factors are 1 and 5. Therefore, the least (smallest) common factor is 1.
Answer: 1 The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1, 2, and 4; the least (smallest) common factor is 1.
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.
The least common multiple of 5 , 4 = 20
The Least Common Multiple of 4, 5 is: 20
The least common multiple of 4 and 5 is 20.
5 and 4 share no common factors aside from 1.
20 and 40 have 4 and 5 as common factors.
The only common factor of 4 and 5 is 1. 4 and 5 are common factors of 20 and 40.
The factors of 5 are 1 and 5. The factors of 10 are 1, 2, 5, and 10. The common factors of 5 and 10 are 1 and 5. Therefore, the least (smallest) common factor is 1. If you mean least common multiple, that would be 10.
