Given numbers are 286,935,272,421

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

The LCM of 286,935,272,421 is 81876080.

Find LCM of 286,935,272,421 with Prime Factorization

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

2 x 11 x 17 x 13 x 5 x 8 x 421 = 81876080

Therefore, the lowest common multiple of 286,935,272,421 is 81876080.

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.

286 x 935 x 272 x 421 = 30621653920

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.

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

935 : 1, 5, 11, 17, 55, 85, 187, 935

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,935,272,421, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

935:5x 11x 17

272:2x 2x 2x 2x 17

421:421

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

2x 11x 17 = 374

Therefore, the value for common factors is 374.

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 = 30621653920/(1x374)

LCM = 30621653920/374

LCM = 81876080

Thus, we can understand that the LCM of 286,935,272,421 is 81876080.
