Given numbers are 861,506,980,644,404

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

The LCM of 861,506,980,644,404 is 3080158620.

Find LCM of 861,506,980,644,404 with Prime Factorization

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

2 x 2 x 7 x 23 x 123 x 11 x 35 x 1 x 101 = 3080158620

Therefore, the lowest common multiple of 861,506,980,644,404 is 3080158620.

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.

861 x 506 x 980 x 644 x 404 = 111082840471680

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

506 : 1, 2, 11, 22, 23, 46, 253, 506

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,506,980,644,404, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

506:2x 11x 23

980:2x 2x 5x 7x 7

644:2x 2x 7x 23

404:2x 2x 101

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 2x 7x 7x 23 = 36064

Therefore, the value for common factors is 36064.

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 = 111082840471680/(1x36064)

LCM = 111082840471680/36064

LCM = 3080158620

Thus, we can understand that the LCM of 861,506,980,644,404 is 3080158620.
