Calculate the LCM of 639,490,132,332

Given numbers are 639,490,132,332

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

The LCM of 639,490,132,332 is 571738860.

Find LCM of 639,490,132,332 with Prime Factorization


2 639, 490, 132, 332
2 639, 245, 66, 166
3 639, 245, 33, 83
213, 245, 11, 83

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

2 x 2 x 3 x 213 x 245 x 11 x 83 = 571738860

Therefore, the lowest common multiple of 639,490,132,332 is 571738860.

LCM Formula to Find Lowest Common Multiple of 639,490,132,332

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 490 x 132 x 332 = 13721732640

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

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,490,132,332, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

490:2x 5x 7x 7

132:2x 2x 3x 11

332:2x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 13721732640/(1x24)

LCM = 13721732640/24

LCM = 571738860

Thus, we can understand that the LCM of 639,490,132,332 is 571738860.
