Given numbers are 620,951,993,876,420

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

The LCM of 620,951,993,876,420 is 99728916420.

Find LCM of 620,951,993,876,420 with Prime Factorization

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

2 x 2 x 3 x 5 x 31 x 317 x 331 x 73 x 7 = 99728916420

Therefore, the lowest common multiple of 620,951,993,876,420 is 99728916420.

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.

620 x 951 x 993 x 876 x 420 = 215414459467200

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

951 : 1, 3, 317, 951

993 : 1, 3, 331, 993

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,951,993,876,420, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

951:3x 317

993:3x 331

876:2x 2x 3x 73

420:2x 2x 3x 5x 7

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 2x 2x 3x 3x 3x 5 = 2160

Therefore, the value for common factors is 2160.

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 = 215414459467200/(1x2160)

LCM = 215414459467200/2160

LCM = 99728916420

Thus, we can understand that the LCM of 620,951,993,876,420 is 99728916420.
