Calculate the LCM of 316,840,563,728

Given numbers are 316,840,563,728

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

The LCM of 316,840,563,728 is 485688840.

Find LCM of 316,840,563,728 with Prime Factorization


2 316, 840, 563, 728
2 158, 420, 563, 364
2 79, 210, 563, 182
7 79, 105, 563, 91
79, 15, 563, 13

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

2 x 2 x 2 x 7 x 79 x 15 x 563 x 13 = 485688840

Therefore, the lowest common multiple of 316,840,563,728 is 485688840.

LCM Formula to Find Lowest Common Multiple of 316,840,563,728

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.

316 x 840 x 563 x 728 = 108794300160

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.

316 : 1, 2, 4, 79, 158, 316

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

563 : 1, 563

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 316,840,563,728, is 1.

Now, the common factors can be found like this.

316:2x 2x 79

840:2x 2x 2x 3x 5x 7

563:563

728:2x 2x 2x 7x 13

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 2x 2x 2x 7 = 224

Therefore, the value for common factors is 224.

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 = 108794300160/(1x224)

LCM = 108794300160/224

LCM = 485688840

Thus, we can understand that the LCM of 316,840,563,728 is 485688840.
