Calculate the LCM of 639,130,846,169

Given numbers are 639,130,846,169

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

The LCM of 639,130,846,169 is 50755770.

Find LCM of 639,130,846,169 with Prime Factorization


2 639, 130, 846, 169
3 639, 65, 423, 169
3 213, 65, 141, 169
13 71, 65, 47, 169
71, 5, 47, 13

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

2 x 3 x 3 x 13 x 71 x 5 x 47 x 13 = 50755770

Therefore, the lowest common multiple of 639,130,846,169 is 50755770.

LCM Formula to Find Lowest Common Multiple of 639,130,846,169

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.

639 x 130 x 846 x 169 = 11876850180

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.

639 : 1, 3, 9, 71, 213, 639

130 : 1, 2, 5, 10, 13, 26, 65, 130

846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,130,846,169, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

130:2x 5x 13

846:2x 3x 3x 47

169:13x 13

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 13 = 234

Therefore, the value for common factors is 234.

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 = 11876850180/(1x234)

LCM = 11876850180/234

LCM = 50755770

Thus, we can understand that the LCM of 639,130,846,169 is 50755770.
