Given numbers are 649,559,377,780

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

The LCM of 649,559,377,780 is 631256340.

Find LCM of 649,559,377,780 with Prime Factorization

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

13 x 649 x 43 x 29 x 60 = 631256340

Therefore, the lowest common multiple of 649,559,377,780 is 631256340.

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.

649 x 559 x 377 x 780 = 106682321460

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.

649 : 1, 11, 59, 649

559 : 1, 13, 43, 559

377 : 1, 13, 29, 377

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,559,377,780, is 1.

Now, the common factors can be found like this.

649:11x 59

559:13x 43

377:13x 29

780:2x 2x 3x 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.

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 106682321460/(1x169)

LCM = 106682321460/169

LCM = 631256340

Thus, we can understand that the LCM of 649,559,377,780 is 631256340.
