Given numbers are 637,749,143

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

The LCM of 637,749,143 is 749749.

Find LCM of 637,749,143 with Prime Factorization

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

7 x 13 x 7 x 107 x 11 = 749749

Therefore, the lowest common multiple of 637,749,143 is 749749.

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 749 x 143 = 68227159

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

749 : 1, 7, 107, 749

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,749,143, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

749:7x 107

143:11x 13

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

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 68227159/(1x91)

LCM = 68227159/91

LCM = 749749

Thus, we can understand that the LCM of 637,749,143 is 749749.

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

• LCM of 955, 284, 790
