Given numbers are 662,889,331,987

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

The LCM of 662,889,331,987 is 82981038.

Find LCM of 662,889,331,987 with Prime Factorization

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

7 x 331 x 2 x 127 x 1 x 141 = 82981038

Therefore, the lowest common multiple of 662,889,331,987 is 82981038.

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.

662 x 889 x 331 x 987 = 192267065046

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.

662 : 1, 2, 331, 662

889 : 1, 7, 127, 889

331 : 1, 331

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,889,331,987, is 1.

Now, the common factors can be found like this.

662:2x 331

889:7x 127

331:331

987:3x 7x 47

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

7x 331 = 2317

Therefore, the value for common factors is 2317.

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 = 192267065046/(1x2317)

LCM = 192267065046/2317

LCM = 82981038

Thus, we can understand that the LCM of 662,889,331,987 is 82981038.
