Calculate the LCM of 649,549,981,642,872

Given numbers are 649,549,981,642,872

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

The LCM of 649,549,981,642,872 is 33244308504.

Find LCM of 649,549,981,642,872 with Prime Factorization


2 649, 549, 981, 642, 872
3 649, 549, 981, 321, 436
3 649, 183, 327, 107, 436
109 649, 61, 109, 107, 436
649, 61, 1, 107, 4

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

2 x 3 x 3 x 109 x 649 x 61 x 1 x 107 x 4 = 33244308504

Therefore, the lowest common multiple of 649,549,981,642,872 is 33244308504.

LCM Formula to Find Lowest Common Multiple of 649,549,981,642,872

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.

649 x 549 x 981 x 642 x 872 = 195675999854544

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.

649 : 1, 11, 59, 649

549 : 1, 3, 9, 61, 183, 549

981 : 1, 3, 9, 109, 327, 981

642 : 1, 2, 3, 6, 107, 214, 321, 642

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,549,981,642,872, is 1.

Now, the common factors can be found like this.

649:11x 59

549:3x 3x 61

981:3x 3x 109

642:2x 3x 107

872:2x 2x 2x 109

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

2x 3x 3x 3x 109 = 5886

Therefore, the value for common factors is 5886.

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 = 195675999854544/(1x5886)

LCM = 195675999854544/5886

LCM = 33244308504

Thus, we can understand that the LCM of 649,549,981,642,872 is 33244308504.
