Given numbers are 647,198,622,391

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

The LCM of 647,198,622,391 is 15577817706.

Find LCM of 647,198,622,391 with Prime Factorization

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

2 x 647 x 99 x 311 x 391 = 15577817706

Therefore, the lowest common multiple of 647,198,622,391 is 15577817706.

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.

647 x 198 x 622 x 391 = 31155635412

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.

647 : 1, 647

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

622 : 1, 2, 311, 622

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,198,622,391, is 1.

Now, the common factors can be found like this.

647:647

198:2x 3x 3x 11

622:2x 311

391:17x 23

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 = 31155635412/(1x2)

LCM = 31155635412/2

LCM = 15577817706

Thus, we can understand that the LCM of 647,198,622,391 is 15577817706.
