Calculate the LCM of 456,391,823,778

Given numbers are 456,391,823,778

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

The LCM of 456,391,823,778 is 57080929512.

Find LCM of 456,391,823,778 with Prime Factorization


2 456, 391, 823, 778
228, 391, 823, 389

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

2 x 228 x 391 x 823 x 389 = 57080929512

Therefore, the lowest common multiple of 456,391,823,778 is 57080929512.

LCM Formula to Find Lowest Common Multiple of 456,391,823,778

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.

456 x 391 x 823 x 778 = 114161859024

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.

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

391 : 1, 17, 23, 391

823 : 1, 823

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,391,823,778, is 1.

Now, the common factors can be found like this.

456:2x 2x 2x 3x 19

391:17x 23

823:823

778:2x 389

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 114161859024/(1x2)

LCM = 114161859024/2

LCM = 57080929512

Thus, we can understand that the LCM of 456,391,823,778 is 57080929512.
