Given numbers are 628,287,647,324

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

The LCM of 628,287,647,324 is 9445628052.

Find LCM of 628,287,647,324 with Prime Factorization

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

2 x 2 x 157 x 287 x 647 x 81 = 9445628052

Therefore, the lowest common multiple of 628,287,647,324 is 9445628052.

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 287 x 647 x 324 = 37782512208

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

287 : 1, 7, 41, 287

647 : 1, 647

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,287,647,324, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

287:7x 41

647:647

324:2x 2x 3x 3x 3x 3

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 37782512208/(1x4)

LCM = 37782512208/4

LCM = 9445628052

Thus, we can understand that the LCM of 628,287,647,324 is 9445628052.
