Given numbers are 638,936,853

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

The LCM of 638,936,853 is 254692152.

Find LCM of 638,936,853 with Prime Factorization

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

2 x 319 x 468 x 853 = 254692152

Therefore, the lowest common multiple of 638,936,853 is 254692152.

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 936 x 853 = 509384304

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

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,936,853, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

936:2x 2x 2x 3x 3x 13

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 509384304/(1x2)

LCM = 509384304/2

LCM = 254692152

Thus, we can understand that the LCM of 638,936,853 is 254692152.

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

• LCM of 240, 245, 836
