5 and 10 5 and 15 5 and 20
1 and 20 is one possible pair.
The Least Common Multiple (LCM) for 5 20 is 20.
The least common multiple is the smallest number that is multiple of two or more numbers. The LCM of 2, 4, and 5 is 20.
Common factor
20 and 40 have 4 and 5 as common factors.
5 and 10 15 and 20 20 and 25
The least common multiple of the numbers 2, 4 and 5 is 20.
The Lowest Common Multiple (LCM) of 4, 5 and 10 is 20
The greatest common factor of the two numbers is 5. 55/5 = 11, 20/5 = 4.
20 and 40
There is neither a greatest common factor nor common factors of a single number, such as 20, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2, 2, and 5. Examples: The common factors of 20 and 70 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 20 and 32 are 1, 2, and 4; the greatest common factor is 4. The common factors of 20 and 140 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.
The greatest common factor of the numbers 20, 35 and 50 is 5.
5 and 10 5 and 15 5 and 20
The GCF of 15 and 20 is 5.Since 15 = 3x5 and 20 = 2 x 2 x 5, the greatest common factor is 5.One way to approach this is to look at the difference between 15 and 20, which is 5. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. Since both 15 and 20 are divisible by 5, the greatest common factor is 5.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 20 are 1, 2, 4, 5, 10, and 20.The common factors are 1 and 5. Therefore, the greatest common factor is 5.The GCF is 5.Divide each number by prime numbers until it you get to 1.For example, 15 --> 5(3)20 --> 2(10) --> 2(2)(5)Compare the end results for both numbers, find the ones they have in common and multiply them together to get the gcf. In this case, it would only be 5.The GCF is 5.
LCM is least common multiple of two or more numbers. LCM of 4 and 5 is 20.
