Given numbers are 898,390,979,646

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

The LCM of 898,390,979,646 is 55372758870.

Find LCM of 898,390,979,646 with Prime Factorization

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

2 x 449 x 195 x 979 x 323 = 55372758870

Therefore, the lowest common multiple of 898,390,979,646 is 55372758870.

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.

898 x 390 x 979 x 646 = 221491035480

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.

898 : 1, 2, 449, 898

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

979 : 1, 11, 89, 979

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,390,979,646, is 1.

Now, the common factors can be found like this.

898:2x 449

390:2x 3x 5x 13

979:11x 89

646:2x 17x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 221491035480/(1x4)

LCM = 221491035480/4

LCM = 55372758870

Thus, we can understand that the LCM of 898,390,979,646 is 55372758870.
