Calculate the LCM of 524,399,195,620

Given numbers are 524,399,195,620

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

The LCM of 524,399,195,620 is 421288140.

Find LCM of 524,399,195,620 with Prime Factorization


2 524, 399, 195, 620
2 262, 399, 195, 310
3 131, 399, 195, 155
5 131, 133, 65, 155
131, 133, 13, 31

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

2 x 2 x 3 x 5 x 131 x 133 x 13 x 31 = 421288140

Therefore, the lowest common multiple of 524,399,195,620 is 421288140.

LCM Formula to Find Lowest Common Multiple of 524,399,195,620

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.

524 x 399 x 195 x 620 = 25277288400

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.

524 : 1, 2, 4, 131, 262, 524

399 : 1, 3, 7, 19, 21, 57, 133, 399

195 : 1, 3, 5, 13, 15, 39, 65, 195

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,399,195,620, is 1.

Now, the common factors can be found like this.

524:2x 2x 131

399:3x 7x 19

195:3x 5x 13

620:2x 2x 5x 31

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

2x 2x 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 25277288400/(1x60)

LCM = 25277288400/60

LCM = 421288140

Thus, we can understand that the LCM of 524,399,195,620 is 421288140.
