Calculate the LCM of 411,548,721,686

Given numbers are 411,548,721,686

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

The LCM of 411,548,721,686 is 58080876.

Find LCM of 411,548,721,686 with Prime Factorization


2 411, 548, 721, 686
7 411, 274, 721, 343
137 411, 274, 103, 49
3, 2, 103, 49

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

2 x 7 x 137 x 3 x 2 x 103 x 49 = 58080876

Therefore, the lowest common multiple of 411,548,721,686 is 58080876.

LCM Formula to Find Lowest Common Multiple of 411,548,721,686

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.

411 x 548 x 721 x 686 = 111399120168

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.

411 : 1, 3, 137, 411

548 : 1, 2, 4, 137, 274, 548

721 : 1, 7, 103, 721

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,548,721,686, is 1.

Now, the common factors can be found like this.

411:3x 137

548:2x 2x 137

721:7x 103

686:2x 7x 7x 7

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

2x 7x 137 = 1918

Therefore, the value for common factors is 1918.

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 = 111399120168/(1x1918)

LCM = 111399120168/1918

LCM = 58080876

Thus, we can understand that the LCM of 411,548,721,686 is 58080876.
