Given numbers are 816,490,907,671

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

The LCM of 816,490,907,671 is 121670712240.

Find LCM of 816,490,907,671 with Prime Factorization

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

2 x 408 x 245 x 907 x 671 = 121670712240

Therefore, the lowest common multiple of 816,490,907,671 is 121670712240.

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 490 x 907 x 671 = 243341424480

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

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

907 : 1, 907

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,490,907,671, is 1.

Now, the common factors can be found like this.

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

490:2x 5x 7x 7

907:907

671:11x 61

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 243341424480/(1x2)

LCM = 243341424480/2

LCM = 121670712240

Thus, we can understand that the LCM of 816,490,907,671 is 121670712240.
