Given numbers are 816,649,928,220

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

The LCM of 816,649,928,220 is 153579360.

Find LCM of 816,649,928,220 with Prime Factorization

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

2 x 2 x 2 x 2 x 11 x 51 x 59 x 58 x 5 = 153579360

Therefore, the lowest common multiple of 816,649,928,220 is 153579360.

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 649 x 928 x 220 = 108119869440

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

649 : 1, 11, 59, 649

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,649,928,220, is 1.

Now, the common factors can be found like this.

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

649:11x 59

928:2x 2x 2x 2x 2x 29

220:2x 2x 5x 11

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 2x 2x 2x 2x 11 = 704

Therefore, the value for common factors is 704.

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 = 108119869440/(1x704)

LCM = 108119869440/704

LCM = 153579360

Thus, we can understand that the LCM of 816,649,928,220 is 153579360.
