Given numbers are 551,812,664,780

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

The LCM of 551,812,664,780 is 499404360.

Find LCM of 551,812,664,780 with Prime Factorization

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

2 x 2 x 29 x 19 x 7 x 166 x 195 = 499404360

Therefore, the lowest common multiple of 551,812,664,780 is 499404360.

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.

551 x 812 x 664 x 780 = 231723623040

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.

551 : 1, 19, 29, 551

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

664 : 1, 2, 4, 8, 83, 166, 332, 664

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,812,664,780, is 1.

Now, the common factors can be found like this.

551:19x 29

812:2x 2x 7x 29

664:2x 2x 2x 83

780:2x 2x 3x 5x 13

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 29 = 464

Therefore, the value for common factors is 464.

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 = 231723623040/(1x464)

LCM = 231723623040/464

LCM = 499404360

Thus, we can understand that the LCM of 551,812,664,780 is 499404360.
