Given numbers are 639,478,956,530,349

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

The LCM of 639,478,956,530,349 is 56497606740.

Find LCM of 639,478,956,530,349 with Prime Factorization

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

2 x 239 x 639 x 1 x 2 x 265 x 349 = 56497606740

Therefore, the lowest common multiple of 639,478,956,530,349 is 56497606740.

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 478 x 956 x 530 x 349 = 54011712043440

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

478 : 1, 2, 239, 478

956 : 1, 2, 4, 239, 478, 956

530 : 1, 2, 5, 10, 53, 106, 265, 530

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,478,956,530,349, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

478:2x 239

956:2x 2x 239

530:2x 5x 53

349:349

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 239 = 956

Therefore, the value for common factors is 956.

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 = 54011712043440/(1x956)

LCM = 54011712043440/956

LCM = 56497606740

Thus, we can understand that the LCM of 639,478,956,530,349 is 56497606740.
