Given numbers are 251,787,642,787

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

The LCM of 251,787,642,787 is 126818754.

Find LCM of 251,787,642,787 with Prime Factorization

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

787 x 251 x 1 x 642 x 1 = 126818754

Therefore, the lowest common multiple of 251,787,642,787 is 126818754.

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.

251 x 787 x 642 x 787 = 99806359398

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.

251 : 1, 251

787 : 1, 787

642 : 1, 2, 3, 6, 107, 214, 321, 642

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,787,642,787, is 1.

Now, the common factors can be found like this.

251:251

787:787

642:2x 3x 107

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 = 99806359398/(1x787)

LCM = 99806359398/787

LCM = 126818754

Thus, we can understand that the LCM of 251,787,642,787 is 126818754.
