Calculate the LCM of 856,889,780,162

Given numbers are 856,889,780,162

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

The LCM of 856,889,780,162 is 4006580760.

Find LCM of 856,889,780,162 with Prime Factorization


2 856, 889, 780, 162
2 428, 889, 390, 81
3 214, 889, 195, 81
214, 889, 65, 27

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

2 x 2 x 3 x 214 x 889 x 65 x 27 = 4006580760

Therefore, the lowest common multiple of 856,889,780,162 is 4006580760.

LCM Formula to Find Lowest Common Multiple of 856,889,780,162

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.

856 x 889 x 780 x 162 = 96157938240

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

889 : 1, 7, 127, 889

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

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,889,780,162, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

889:7x 127

780:2x 2x 3x 5x 13

162:2x 3x 3x 3x 3

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 3 = 24

Therefore, the value for common factors is 24.

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 = 96157938240/(1x24)

LCM = 96157938240/24

LCM = 4006580760

Thus, we can understand that the LCM of 856,889,780,162 is 4006580760.
