Given numbers are 391,787,508,451,787

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

The LCM of 391,787,508,451,787 is 70500426436.

Find LCM of 391,787,508,451,787 with Prime Factorization

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

787 x 391 x 1 x 508 x 451 x 1 = 70500426436

Therefore, the lowest common multiple of 391,787,508,451,787 is 70500426436.

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.

391 x 787 x 508 x 451 x 787 = 55483835605132

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.

391 : 1, 17, 23, 391

787 : 1, 787

508 : 1, 2, 4, 127, 254, 508

451 : 1, 11, 41, 451

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,787,508,451,787, is 1.

Now, the common factors can be found like this.

391:17x 23

787:787

508:2x 2x 127

451:11x 41

787:787

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

787 = 787

Therefore, the value for common factors is 787.

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 = 55483835605132/(1x787)

LCM = 55483835605132/787

LCM = 70500426436

Thus, we can understand that the LCM of 391,787,508,451,787 is 70500426436.
