The GCF of 18, 21, and 54 is 3.
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
Answer: 1 The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3; the least (smallest) common factor is 1.
The least common factor of any set of numbers is 1.
The least common multiple (LCM) of 18, 21, and 56 is 504.
The least common factor of any set of integers is 1.
The least common factor of any set of integers is 1.
You need at least two numbers to find a GCF.
The greatest common factor of 18 and 21 is 3.
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 21 are 1, 3, 7, and 21. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors they have in common are 1 and 3. So, the least (or lowest) common factor is 1. Note: The least common factor of two or more positive integers will always be 1.
The least common factor is: 1
The Greatest Common Factor of 9, 18, 21: 3
The least common factor is: 1
The least common multiple of 21 , 18 = 126
least common multiple for 18 and 21 is 126.
The least common factor of any set of integers is 1.
The least common factor of any set of integers is 1.
