The LCM of 643,567,418,628 is 47851985412.

Find LCM of 643,567,418,628 with Prime Factorization


2 643, 567, 418, 628
643, 567, 209, 314

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

2 x 643 x 567 x 209 x 314 = 47851985412

Therefore, the lowest common multiple of 643,567,418,628 is 47851985412.

LCM Formula to Find Lowest Common Multiple of 643,567,418,628

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.

643 x 567 x 418 x 628 = 95703970824

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.

643 : 1, 643

567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567

418 : 1, 2, 11, 19, 22, 38, 209, 418

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,567,418,628, is 1.

Now, the common factors can be found like this.

643:643

567:3x 3x 3x 3x 7

418:2x 11x 19

628:2x 2x 157

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

2 = 2

Therefore, the value for common factors is 2.

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 = 95703970824/(1x2)

LCM = 95703970824/2

LCM = 47851985412

Thus, we can understand that the LCM of 643,567,418,628 is 47851985412.
