Calculate the LCM of 851,415,138,166

Given numbers are 851,415,138,166

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

The LCM of 851,415,138,166 is 2118990.

Find LCM of 851,415,138,166 with Prime Factorization


2 851, 415, 138, 166
23 851, 415, 69, 83
83 37, 415, 3, 83
37, 5, 3, 1

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

2 x 23 x 83 x 37 x 5 x 3 x 1 = 2118990

Therefore, the lowest common multiple of 851,415,138,166 is 2118990.

LCM Formula to Find Lowest Common Multiple of 851,415,138,166

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.

851 x 415 x 138 x 166 = 8090303820

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.

851 : 1, 23, 37, 851

415 : 1, 5, 83, 415

138 : 1, 2, 3, 6, 23, 46, 69, 138

166 : 1, 2, 83, 166

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,415,138,166, is 1.

Now, the common factors can be found like this.

851:23x 37

415:5x 83

138:2x 3x 23

166:2x 83

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 83 = 3818

Therefore, the value for common factors is 3818.

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 = 8090303820/(1x3818)

LCM = 8090303820/3818

LCM = 2118990

Thus, we can understand that the LCM of 851,415,138,166 is 2118990.
