Given numbers are 842,115,204,974

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

The LCM of 842,115,204,974 is 4809933420.

Find LCM of 842,115,204,974 with Prime Factorization

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

2 x 421 x 115 x 102 x 487 = 4809933420

Therefore, the lowest common multiple of 842,115,204,974 is 4809933420.

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.

842 x 115 x 204 x 974 = 19239733680

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.

842 : 1, 2, 421, 842

115 : 1, 5, 23, 115

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,115,204,974, is 1.

Now, the common factors can be found like this.

842:2x 421

115:5x 23

204:2x 2x 3x 17

974:2x 487

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 = 19239733680/(1x4)

LCM = 19239733680/4

LCM = 4809933420

Thus, we can understand that the LCM of 842,115,204,974 is 4809933420.
