Given numbers are 637,553,433

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

The LCM of 637,553,433 is 21789859.

Find LCM of 637,553,433 with Prime Factorization

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

7 x 91 x 79 x 433 = 21789859

Therefore, the lowest common multiple of 637,553,433 is 21789859.

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 553 x 433 = 152529013

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

553 : 1, 7, 79, 553

433 : 1, 433

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,553,433, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

553:7x 79

433:433

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 = 152529013/(1x7)

LCM = 152529013/7

LCM = 21789859

Thus, we can understand that the LCM of 637,553,433 is 21789859.

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

• LCM of 519, 798, 178
