Calculate the LCM of 208,649,891,143

Given numbers are 208,649,891,143

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

The LCM of 208,649,891,143 is 10934352.

Find LCM of 208,649,891,143 with Prime Factorization


11 208, 649, 891, 143
13 208, 59, 81, 13
16, 59, 81, 1

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

11 x 13 x 16 x 59 x 81 x 1 = 10934352

Therefore, the lowest common multiple of 208,649,891,143 is 10934352.

LCM Formula to Find Lowest Common Multiple of 208,649,891,143

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.

208 x 649 x 891 x 143 = 17199735696

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.

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

649 : 1, 11, 59, 649

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,649,891,143, is 1.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

649:11x 59

891:3x 3x 3x 3x 11

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.

11x 11x 13 = 1573

Therefore, the value for common factors is 1573.

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 = 17199735696/(1x1573)

LCM = 17199735696/1573

LCM = 10934352

Thus, we can understand that the LCM of 208,649,891,143 is 10934352.
