Calculate the LCM of 618,813,749,309,103

Given numbers are 618,813,749,309,103

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

The LCM of 618,813,749,309,103 is 125441022.

Find LCM of 618,813,749,309,103 with Prime Factorization


3 618, 813, 749, 309, 103
103 206, 271, 749, 103, 103
2, 271, 749, 1, 1

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

3 x 103 x 2 x 271 x 749 x 1 x 1 = 125441022

Therefore, the lowest common multiple of 618,813,749,309,103 is 125441022.

LCM Formula to Find Lowest Common Multiple of 618,813,749,309,103

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.

618 x 813 x 749 x 309 x 103 = 11977234221582

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

813 : 1, 3, 271, 813

749 : 1, 7, 107, 749

309 : 1, 3, 103, 309

103 : 1, 103

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,813,749,309,103, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

813:3x 271

749:7x 107

309:3x 103

103:103

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

3x 3x 103x 103 = 95481

Therefore, the value for common factors is 95481.

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 = 11977234221582/(1x95481)

LCM = 11977234221582/95481

LCM = 125441022

Thus, we can understand that the LCM of 618,813,749,309,103 is 125441022.
