Calculate the LCM of 971,916,808,238

Given numbers are 971,916,808,238

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

The LCM of 971,916,808,238 is 21380262568.

Find LCM of 971,916,808,238 with Prime Factorization


2 971, 916, 808, 238
2 971, 458, 404, 119
971, 229, 202, 119

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

2 x 2 x 971 x 229 x 202 x 119 = 21380262568

Therefore, the lowest common multiple of 971,916,808,238 is 21380262568.

LCM Formula to Find Lowest Common Multiple of 971,916,808,238

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.

971 x 916 x 808 x 238 = 171042100544

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.

971 : 1, 971

916 : 1, 2, 4, 229, 458, 916

808 : 1, 2, 4, 8, 101, 202, 404, 808

238 : 1, 2, 7, 14, 17, 34, 119, 238

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,916,808,238, is 1.

Now, the common factors can be found like this.

971:971

916:2x 2x 229

808:2x 2x 2x 101

238:2x 7x 17

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 2 = 8

Therefore, the value for common factors is 8.

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 = 171042100544/(1x8)

LCM = 171042100544/8

LCM = 21380262568

Thus, we can understand that the LCM of 971,916,808,238 is 21380262568.
