Find LCM of 811,156,616,861 with Prime Factorization


2 811, 156, 616, 861
2 811, 78, 308, 861
3 811, 39, 154, 861
7 811, 13, 154, 287
811, 13, 22, 41

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

2 x 2 x 3 x 7 x 811 x 13 x 22 x 41 = 798822024

Therefore, the lowest common multiple of 811,156,616,861 is 798822024.

LCM Formula to Find Lowest Common Multiple of 811,156,616,861

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.

811 x 156 x 616 x 861 = 67101050016

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.

811 : 1, 811

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,156,616,861, is 1.

Now, the common factors can be found like this.

811:811

156:2x 2x 3x 13

616:2x 2x 2x 7x 11

861:3x 7x 41

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 3x 7 = 84

Therefore, the value for common factors is 84.

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 = 67101050016/(1x84)

LCM = 67101050016/84

LCM = 798822024

Thus, we can understand that the LCM of 811,156,616,861 is 798822024.
