Given numbers are 60,11,638

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 60,11,638 is 19140.

Find LCM of 60,11,638 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 11 x 30 x 1 x 29 = 19140

Therefore, the lowest common multiple of 60,11,638 is 19140.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

60 x 11 x 638 = 421080

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

11 : 1, 11

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 60,11,638, is 1.

Now, the common factors can be found like this.

60:2x 2x 3x 5

11:11

638:2x 11x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 11 = 22

Therefore, the value for common factors is 22.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 421080/(1x22)

LCM = 421080/22

LCM = 19140

Thus, we can understand that the LCM of 60,11,638 is 19140.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 18, 30, 829
• LCM of 29, 79, 972
