Given numbers are 645,641,387,767,996

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

The LCM of 645,641,387,767,996 is 315843865740.

Find LCM of 645,641,387,767,996 with Prime Factorization

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

3 x 43 x 5 x 641 x 3 x 767 x 332 = 315843865740

Therefore, the lowest common multiple of 645,641,387,767,996 is 315843865740.

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.

645 x 641 x 387 x 767 x 996 = 122231576041380

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

641 : 1, 641

387 : 1, 3, 9, 43, 129, 387

767 : 1, 13, 59, 767

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,641,387,767,996, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

641:641

387:3x 3x 43

767:13x 59

996:2x 2x 3x 83

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

3x 3x 43 = 387

Therefore, the value for common factors is 387.

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 = 122231576041380/(1x387)

LCM = 122231576041380/387

LCM = 315843865740

Thus, we can understand that the LCM of 645,641,387,767,996 is 315843865740.
