Calculate the LCM of 856,991,107,836

Given numbers are 856,991,107,836

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

The LCM of 856,991,107,836 is 177293864.

Find LCM of 856,991,107,836 with Prime Factorization


2 856, 991, 107, 836
2 428, 991, 107, 418
107 214, 991, 107, 209
2, 991, 1, 209

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

2 x 2 x 107 x 2 x 991 x 1 x 209 = 177293864

Therefore, the lowest common multiple of 856,991,107,836 is 177293864.

LCM Formula to Find Lowest Common Multiple of 856,991,107,836

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 991 x 107 x 836 = 75881773792

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

991 : 1, 991

107 : 1, 107

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,991,107,836, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

991:991

107:107

836:2x 2x 11x 19

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 107 = 428

Therefore, the value for common factors is 428.

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 = 75881773792/(1x428)

LCM = 75881773792/428

LCM = 177293864

Thus, we can understand that the LCM of 856,991,107,836 is 177293864.
