Given numbers are 406,754,971,816

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

The LCM of 406,754,971,816 is 2090974704.

Find LCM of 406,754,971,816 with Prime Factorization

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

2 x 29 x 7 x 13 x 971 x 408 = 2090974704

Therefore, the lowest common multiple of 406,754,971,816 is 2090974704.

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.

406 x 754 x 971 x 816 = 242553065664

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

754 : 1, 2, 13, 26, 29, 58, 377, 754

971 : 1, 971

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,754,971,816, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

754:2x 13x 29

971:971

816:2x 2x 2x 2x 3x 17

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 29 = 116

Therefore, the value for common factors is 116.

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 = 242553065664/(1x116)

LCM = 242553065664/116

LCM = 2090974704

Thus, we can understand that the LCM of 406,754,971,816 is 2090974704.
