Given numbers are 402,826,790,857

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

The LCM of 402,826,790,857 is 56202291390.

Find LCM of 402,826,790,857 with Prime Factorization

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

2 x 201 x 413 x 395 x 857 = 56202291390

Therefore, the lowest common multiple of 402,826,790,857 is 56202291390.

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.

402 x 826 x 790 x 857 = 224809165560

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

826 : 1, 2, 7, 14, 59, 118, 413, 826

790 : 1, 2, 5, 10, 79, 158, 395, 790

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,826,790,857, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

826:2x 7x 59

790:2x 5x 79

857:857

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 = 224809165560/(1x4)

LCM = 224809165560/4

LCM = 56202291390

Thus, we can understand that the LCM of 402,826,790,857 is 56202291390.
