Calculate the LCM of 845,907,478,638

Given numbers are 845,907,478,638

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

The LCM of 845,907,478,638 is 116864492030.

Find LCM of 845,907,478,638 with Prime Factorization


2 845, 907, 478, 638
845, 907, 239, 319

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

2 x 845 x 907 x 239 x 319 = 116864492030

Therefore, the lowest common multiple of 845,907,478,638 is 116864492030.

LCM Formula to Find Lowest Common Multiple of 845,907,478,638

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.

845 x 907 x 478 x 638 = 233728984060

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.

845 : 1, 5, 13, 65, 169, 845

907 : 1, 907

478 : 1, 2, 239, 478

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,907,478,638, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

907:907

478:2x 239

638:2x 11x 29

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 = 233728984060/(1x2)

LCM = 233728984060/2

LCM = 116864492030

Thus, we can understand that the LCM of 845,907,478,638 is 116864492030.
