Calculate the LCM of 620,995,342

Given numbers are 620,995,342

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

The LCM of 620,995,342 is 21097980.

Find LCM of 620,995,342 with Prime Factorization


2 620, 995, 342
5 310, 995, 171
62, 199, 171

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

2 x 5 x 62 x 199 x 171 = 21097980

Therefore, the lowest common multiple of 620,995,342 is 21097980.

LCM Formula to Find Lowest Common Multiple of 620,995,342

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.

620 x 995 x 342 = 210979800

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

995 : 1, 5, 199, 995

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,995,342, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

995:5x 199

342:2x 3x 3x 19

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 210979800/(1x10)

LCM = 210979800/10

LCM = 21097980

Thus, we can understand that the LCM of 620,995,342 is 21097980.
