Given numbers are 616,869,660,812

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

The LCM of 616,869,660,812 is 21168840.

Find LCM of 616,869,660,812 with Prime Factorization

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

2 x 2 x 7 x 11 x 2 x 79 x 15 x 29 = 21168840

Therefore, the lowest common multiple of 616,869,660,812 is 21168840.

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.

616 x 869 x 660 x 812 = 286880119680

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.

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

869 : 1, 11, 79, 869

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,869,660,812, is 1.

Now, the common factors can be found like this.

616:2x 2x 2x 7x 11

869:11x 79

660:2x 2x 3x 5x 11

812:2x 2x 7x 29

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 7x 11x 11 = 13552

Therefore, the value for common factors is 13552.

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 = 286880119680/(1x13552)

LCM = 286880119680/13552

LCM = 21168840

Thus, we can understand that the LCM of 616,869,660,812 is 21168840.
