Given numbers are 638,493,853

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

The LCM of 638,493,853 is 9251638.

Find LCM of 638,493,853 with Prime Factorization

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

29 x 22 x 17 x 853 = 9251638

Therefore, the lowest common multiple of 638,493,853 is 9251638.

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.

638 x 493 x 853 = 268297502

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.

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

493 : 1, 17, 29, 493

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,493,853, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

493:17x 29

853:853

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

29 = 29

Therefore, the value for common factors is 29.

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 = 268297502/(1x29)

LCM = 268297502/29

LCM = 9251638

Thus, we can understand that the LCM of 638,493,853 is 9251638.

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

• LCM of 493, 122, 769
