Given numbers are 639,983,983

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

The LCM of 639,983,983 is 628137.

Find LCM of 639,983,983 with Prime Factorization

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

983 x 639 x 1 x 1 = 628137

Therefore, the lowest common multiple of 639,983,983 is 628137.

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.

639 x 983 x 983 = 617458671

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.

639 : 1, 3, 9, 71, 213, 639

983 : 1, 983

983 : 1, 983

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,983,983, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

983:983

983:983

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

983 = 983

Therefore, the value for common factors is 983.

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 = 617458671/(1x983)

LCM = 617458671/983

LCM = 628137

Thus, we can understand that the LCM of 639,983,983 is 628137.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 501, 135, 788
• LCM of 510, 123, 637
