Given numbers are 121,442,974,286,507

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

The LCM of 121,442,974,286,507 is 1015783626.

Find LCM of 121,442,974,286,507 with Prime Factorization

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

2 x 11 x 13 x 11 x 17 x 487 x 1 x 39 = 1015783626

Therefore, the lowest common multiple of 121,442,974,286,507 is 1015783626.

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.

121 x 442 x 974 x 286 x 507 = 7553367042936

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.

121 : 1, 11, 121

442 : 1, 2, 13, 17, 26, 34, 221, 442

974 : 1, 2, 487, 974

286 : 1, 2, 11, 13, 22, 26, 143, 286

507 : 1, 3, 13, 39, 169, 507

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,442,974,286,507, is 1.

Now, the common factors can be found like this.

121:11x 11

442:2x 13x 17

974:2x 487

286:2x 11x 13

507:3x 13x 13

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 11x 13x 13 = 7436

Therefore, the value for common factors is 7436.

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 = 7553367042936/(1x7436)

LCM = 7553367042936/7436

LCM = 1015783626

Thus, we can understand that the LCM of 121,442,974,286,507 is 1015783626.
