Given numbers are 643,502,516,763

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

The LCM of 643,502,516,763 is 63541715244.

Find LCM of 643,502,516,763 with Prime Factorization

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

2 x 643 x 251 x 258 x 763 = 63541715244

Therefore, the lowest common multiple of 643,502,516,763 is 63541715244.

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.

643 x 502 x 516 x 763 = 127083430488

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.

643 : 1, 643

502 : 1, 2, 251, 502

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

763 : 1, 7, 109, 763

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,502,516,763, is 1.

Now, the common factors can be found like this.

643:643

502:2x 251

516:2x 2x 3x 43

763:7x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 127083430488/(1x2)

LCM = 127083430488/2

LCM = 63541715244

Thus, we can understand that the LCM of 643,502,516,763 is 63541715244.
