Given numbers are 387,546,780,853

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

The LCM of 387,546,780,853 is 600802020.

Find LCM of 387,546,780,853 with Prime Factorization

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

2 x 3 x 13 x 129 x 7 x 10 x 853 = 600802020

Therefore, the lowest common multiple of 387,546,780,853 is 600802020.

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.

387 x 546 x 780 x 853 = 140587672680

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.

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

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

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

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,546,780,853, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

546:2x 3x 7x 13

780:2x 2x 3x 5x 13

853:853

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

2x 3x 3x 13 = 234

Therefore, the value for common factors is 234.

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 = 140587672680/(1x234)

LCM = 140587672680/234

LCM = 600802020

Thus, we can understand that the LCM of 387,546,780,853 is 600802020.
