Given numbers are 628,781,471,614

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

The LCM of 628,781,471,614 is 451721028.

Find LCM of 628,781,471,614 with Prime Factorization

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

2 x 157 x 2 x 781 x 3 x 307 = 451721028

Therefore, the lowest common multiple of 628,781,471,614 is 451721028.

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 471 x 614 = 141840402792

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

471 : 1, 3, 157, 471

614 : 1, 2, 307, 614

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,781,471,614, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

781:11x 71

471:3x 157

614:2x 307

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 141840402792/(1x314)

LCM = 141840402792/314

LCM = 451721028

Thus, we can understand that the LCM of 628,781,471,614 is 451721028.
