Given numbers are 816,440,643,541

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

The LCM of 816,440,643,541 is 15612091440.

Find LCM of 816,440,643,541 with Prime Factorization

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

2 x 2 x 2 x 102 x 55 x 643 x 541 = 15612091440

Therefore, the lowest common multiple of 816,440,643,541 is 15612091440.

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 440 x 643 x 541 = 124896731520

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

643 : 1, 643

541 : 1, 541

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,440,643,541, is 1.

Now, the common factors can be found like this.

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

440:2x 2x 2x 5x 11

643:643

541:541

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 2 = 8

Therefore, the value for common factors is 8.

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 = 124896731520/(1x8)

LCM = 124896731520/8

LCM = 15612091440

Thus, we can understand that the LCM of 816,440,643,541 is 15612091440.
