Calculate the LCM of 889,418,721,992

Given numbers are 889,418,721,992

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

The LCM of 889,418,721,992 is 18984402976.

Find LCM of 889,418,721,992 with Prime Factorization


2 889, 418, 721, 992
7 889, 209, 721, 496
127, 209, 103, 496

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

2 x 7 x 127 x 209 x 103 x 496 = 18984402976

Therefore, the lowest common multiple of 889,418,721,992 is 18984402976.

LCM Formula to Find Lowest Common Multiple of 889,418,721,992

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.

889 x 418 x 721 x 992 = 265781641664

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.

889 : 1, 7, 127, 889

418 : 1, 2, 11, 19, 22, 38, 209, 418

721 : 1, 7, 103, 721

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,418,721,992, is 1.

Now, the common factors can be found like this.

889:7x 127

418:2x 11x 19

721:7x 103

992:2x 2x 2x 2x 2x 31

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 265781641664/(1x14)

LCM = 265781641664/14

LCM = 18984402976

Thus, we can understand that the LCM of 889,418,721,992 is 18984402976.
