Given numbers are 628,781,416,143

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

The LCM of 628,781,416,143 is 51008672.

Find LCM of 628,781,416,143 with Prime Factorization

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

2 x 2 x 11 x 13 x 157 x 71 x 8 x 1 = 51008672

Therefore, the lowest common multiple of 628,781,416,143 is 51008672.

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.

628 x 781 x 416 x 143 = 29176960384

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.

628 : 1, 2, 4, 157, 314, 628

781 : 1, 11, 71, 781

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,781,416,143, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

781:11x 71

416:2x 2x 2x 2x 2x 13

143:11x 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 11x 13 = 572

Therefore, the value for common factors is 572.

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 = 29176960384/(1x572)

LCM = 29176960384/572

LCM = 51008672

Thus, we can understand that the LCM of 628,781,416,143 is 51008672.
