Calculate the LCM of 649,386,957,580

Given numbers are 649,386,957,580

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

The LCM of 649,386,957,580 is 217947180.

Find LCM of 649,386,957,580 with Prime Factorization


2 649, 386, 957, 580
11 649, 193, 957, 290
29 59, 193, 87, 290
59, 193, 3, 10

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

2 x 11 x 29 x 59 x 193 x 3 x 10 = 217947180

Therefore, the lowest common multiple of 649,386,957,580 is 217947180.

LCM Formula to Find Lowest Common Multiple of 649,386,957,580

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.

649 x 386 x 957 x 580 = 139050300840

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.

649 : 1, 11, 59, 649

386 : 1, 2, 193, 386

957 : 1, 3, 11, 29, 33, 87, 319, 957

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,386,957,580, is 1.

Now, the common factors can be found like this.

649:11x 59

386:2x 193

957:3x 11x 29

580:2x 2x 5x 29

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

2x 11x 29 = 638

Therefore, the value for common factors is 638.

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 = 139050300840/(1x638)

LCM = 139050300840/638

LCM = 217947180

Thus, we can understand that the LCM of 649,386,957,580 is 217947180.
