Given numbers are 816,497,561,684

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

The LCM of 816,497,561,684 is 254281104.

Find LCM of 816,497,561,684 with Prime Factorization

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

2 x 2 x 3 x 17 x 4 x 497 x 11 x 57 = 254281104

Therefore, the lowest common multiple of 816,497,561,684 is 254281104.

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.

816 x 497 x 561 x 684 = 155620035648

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.

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

497 : 1, 7, 71, 497

561 : 1, 3, 11, 17, 33, 51, 187, 561

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,497,561,684, is 1.

Now, the common factors can be found like this.

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

497:7x 71

561:3x 11x 17

684:2x 2x 3x 3x 19

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 3x 3x 17 = 612

Therefore, the value for common factors is 612.

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 = 155620035648/(1x612)

LCM = 155620035648/612

LCM = 254281104

Thus, we can understand that the LCM of 816,497,561,684 is 254281104.
