Calculate the LCM of 846,431,278,768

Given numbers are 846,431,278,768

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

The LCM of 846,431,278,768 is 6487425792.

Find LCM of 846,431,278,768 with Prime Factorization


2 846, 431, 278, 768
3 423, 431, 139, 384
141, 431, 139, 128

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

2 x 3 x 141 x 431 x 139 x 128 = 6487425792

Therefore, the lowest common multiple of 846,431,278,768 is 6487425792.

LCM Formula to Find Lowest Common Multiple of 846,431,278,768

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.

846 x 431 x 278 x 768 = 77849109504

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.

846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846

431 : 1, 431

278 : 1, 2, 139, 278

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,431,278,768, is 1.

Now, the common factors can be found like this.

846:2x 3x 3x 47

431:431

278:2x 139

768:2x 2x 2x 2x 2x 2x 2x 2x 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 3 = 12

Therefore, the value for common factors is 12.

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 = 77849109504/(1x12)

LCM = 77849109504/12

LCM = 6487425792

Thus, we can understand that the LCM of 846,431,278,768 is 6487425792.
