Given numbers are 421,616,818,366

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

The LCM of 421,616,818,366 is 19410521592.

Find LCM of 421,616,818,366 with Prime Factorization

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

2 x 421 x 308 x 409 x 183 = 19410521592

Therefore, the lowest common multiple of 421,616,818,366 is 19410521592.

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 616 x 818 x 366 = 77642086368

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

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

818 : 1, 2, 409, 818

366 : 1, 2, 3, 6, 61, 122, 183, 366

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,616,818,366, is 1.

Now, the common factors can be found like this.

421:421

616:2x 2x 2x 7x 11

818:2x 409

366:2x 3x 61

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 = 77642086368/(1x4)

LCM = 77642086368/4

LCM = 19410521592

Thus, we can understand that the LCM of 421,616,818,366 is 19410521592.
