Calculate the LCM of 858,851,664,691

Given numbers are 858,851,664,691

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

The LCM of 858,851,664,691 is 167507007096.

Find LCM of 858,851,664,691 with Prime Factorization


2 858, 851, 664, 691
429, 851, 332, 691

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

2 x 429 x 851 x 332 x 691 = 167507007096

Therefore, the lowest common multiple of 858,851,664,691 is 167507007096.

LCM Formula to Find Lowest Common Multiple of 858,851,664,691

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.

858 x 851 x 664 x 691 = 335014014192

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

851 : 1, 23, 37, 851

664 : 1, 2, 4, 8, 83, 166, 332, 664

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,851,664,691, is 1.

Now, the common factors can be found like this.

858:2x 3x 11x 13

851:23x 37

664:2x 2x 2x 83

691:691

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 = 335014014192/(1x2)

LCM = 335014014192/2

LCM = 167507007096

Thus, we can understand that the LCM of 858,851,664,691 is 167507007096.
