Calculate the LCM of 639,402,456,428,650

Given numbers are 639,402,456,428,650

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

The LCM of 639,402,456,428,650 is 226300955400.

Find LCM of 639,402,456,428,650 with Prime Factorization


2 639, 402, 456, 428, 650
2 639, 201, 228, 214, 325
3 639, 201, 114, 107, 325
213, 67, 38, 107, 325

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

2 x 2 x 3 x 213 x 67 x 38 x 107 x 325 = 226300955400

Therefore, the lowest common multiple of 639,402,456,428,650 is 226300955400.

LCM Formula to Find Lowest Common Multiple of 639,402,456,428,650

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 402 x 456 x 428 x 650 = 32587337577600

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

428 : 1, 2, 4, 107, 214, 428

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,402,456,428,650, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

402:2x 3x 67

456:2x 2x 2x 3x 19

428:2x 2x 107

650:2x 5x 5x 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 2x 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 32587337577600/(1x144)

LCM = 32587337577600/144

LCM = 226300955400

Thus, we can understand that the LCM of 639,402,456,428,650 is 226300955400.
