1, 2, 3, 6, i think that is all
The least common multiple of 18 , 30 , 60 = 180
The common factors of 30 and 60 are 1, 2, 3, 5, 6, 10, 15 and 30.
All the factors of 30.
Since 30 is a factor of 60, all of its factors are common.
For 18, 2 and 3 For 30 and 60, 2, 3 and 5
Since 30 is a factor of 60, all the factors of 30 will be common to 60.
The common factors are: 1, 2, 3, 5, 6, 10, 15, 30
The common factors are: 1, 2, 3, 6.
The Least Common Multiple (LCM) for 60 30 18 is 180.
15 and 30 are factors of 60. The factors of 60 include the factors of 15 and 30. 45 is not a factor of 60.
The greatest common factor is 6. The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.The greatest common factor can also be determined from the prime factors.The prime factors of 18 are 2, 3, and 3.The prime factors of 60 are 2, 2, 3, and 5.The prime factors they have in common are 2 and 3, so the greatest common factor is 2 x 3 = 6.The GCF is 6.
One way to determine the common factors is to find all the factors of the numbers and compare them. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The common factors are 1, 2, 3, 5, 6, 10, 15, and 30. This also means the greatest common factor is 30.
