Given numbers are 551,864,881,781,428

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

The LCM of 551,864,881,781,428 is 35049034693728.

Find LCM of 551,864,881,781,428 with Prime Factorization

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

2 x 2 x 551 x 216 x 881 x 781 x 107 = 35049034693728

Therefore, the lowest common multiple of 551,864,881,781,428 is 35049034693728.

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 864 x 881 x 781 x 428 = 140196138774912

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

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

881 : 1, 881

781 : 1, 11, 71, 781

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,864,881,781,428, is 1.

Now, the common factors can be found like this.

551:19x 29

864:2x 2x 2x 2x 2x 3x 3x 3

881:881

781:11x 71

428:2x 2x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 140196138774912/(1x4)

LCM = 140196138774912/4

LCM = 35049034693728

Thus, we can understand that the LCM of 551,864,881,781,428 is 35049034693728.
