Calculate the LCM of 642,259,851,368

Given numbers are 642,259,851,368

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

The LCM of 642,259,851,368 is 30595152.

Find LCM of 642,259,851,368 with Prime Factorization


2 642, 259, 851, 368
23 321, 259, 851, 184
37 321, 259, 37, 8
321, 7, 1, 8

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

2 x 23 x 37 x 321 x 7 x 1 x 8 = 30595152

Therefore, the lowest common multiple of 642,259,851,368 is 30595152.

LCM Formula to Find Lowest Common Multiple of 642,259,851,368

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.

642 x 259 x 851 x 368 = 52072948704

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.

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

259 : 1, 7, 37, 259

851 : 1, 23, 37, 851

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,259,851,368, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

259:7x 37

851:23x 37

368:2x 2x 2x 2x 23

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

2x 23x 37 = 1702

Therefore, the value for common factors is 1702.

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 = 52072948704/(1x1702)

LCM = 52072948704/1702

LCM = 30595152

Thus, we can understand that the LCM of 642,259,851,368 is 30595152.
