Given numbers are 163,690,684,780,784

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

The LCM of 163,690,684,780,784 is 32669385840.

Find LCM of 163,690,684,780,784 with Prime Factorization

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

2 x 2 x 3 x 5 x 163 x 23 x 57 x 13 x 196 = 32669385840

Therefore, the lowest common multiple of 163,690,684,780,784 is 32669385840.

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.

163 x 690 x 684 x 780 x 784 = 47043915609600

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.

163 : 1, 163

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

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

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,690,684,780,784, is 1.

Now, the common factors can be found like this.

163:163

690:2x 3x 5x 23

684:2x 2x 3x 3x 19

780:2x 2x 3x 5x 13

784:2x 2x 2x 2x 7x 7

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 3x 3x 5 = 1440

Therefore, the value for common factors is 1440.

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 = 47043915609600/(1x1440)

LCM = 47043915609600/1440

LCM = 32669385840

Thus, we can understand that the LCM of 163,690,684,780,784 is 32669385840.
