Calculate the LCM of 989,862,862,886

Given numbers are 989,862,862,886

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

The LCM of 989,862,862,886 is 377665474.

Find LCM of 989,862,862,886 with Prime Factorization


2 989, 862, 862, 886
431 989, 431, 431, 443
989, 1, 1, 443

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

2 x 431 x 989 x 1 x 1 x 443 = 377665474

Therefore, the lowest common multiple of 989,862,862,886 is 377665474.

LCM Formula to Find Lowest Common Multiple of 989,862,862,886

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.

989 x 862 x 862 x 886 = 651095277176

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.

989 : 1, 23, 43, 989

862 : 1, 2, 431, 862

862 : 1, 2, 431, 862

886 : 1, 2, 443, 886

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,862,862,886, is 1.

Now, the common factors can be found like this.

989:23x 43

862:2x 431

862:2x 431

886:2x 443

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 431 = 1724

Therefore, the value for common factors is 1724.

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 = 651095277176/(1x1724)

LCM = 651095277176/1724

LCM = 377665474

Thus, we can understand that the LCM of 989,862,862,886 is 377665474.
