Given numbers are 637,133,218

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

The LCM of 637,133,218 is 2638454.

Find LCM of 637,133,218 with Prime Factorization

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

7 x 91 x 19 x 218 = 2638454

Therefore, the lowest common multiple of 637,133,218 is 2638454.

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.

637 x 133 x 218 = 18469178

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.

637 : 1, 7, 13, 49, 91, 637

133 : 1, 7, 19, 133

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,133,218, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

133:7x 19

218:2x 109

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

7 = 7

Therefore, the value for common factors is 7.

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 = 18469178/(1x7)

LCM = 18469178/7

LCM = 2638454

Thus, we can understand that the LCM of 637,133,218 is 2638454.

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

• LCM of 652, 747, 311
• LCM of 330, 120, 530
