Given numbers are 421,528,520,718

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

The LCM of 421,528,520,718 is 5187090480.

Find LCM of 421,528,520,718 with Prime Factorization

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

2 x 2 x 2 x 421 x 66 x 65 x 359 = 5187090480

Therefore, the lowest common multiple of 421,528,520,718 is 5187090480.

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.

421 x 528 x 520 x 718 = 82993447680

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.

421 : 1, 421

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

718 : 1, 2, 359, 718

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,528,520,718, is 1.

Now, the common factors can be found like this.

421:421

528:2x 2x 2x 2x 3x 11

520:2x 2x 2x 5x 13

718:2x 359

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 82993447680/(1x16)

LCM = 82993447680/16

LCM = 5187090480

Thus, we can understand that the LCM of 421,528,520,718 is 5187090480.
