Calculate the LCM of 618,994,949,557

Given numbers are 618,994,949,557

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

The LCM of 618,994,949,557 is 162355225578.

Find LCM of 618,994,949,557 with Prime Factorization


2 618, 994, 949, 557
309, 497, 949, 557

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

2 x 309 x 497 x 949 x 557 = 162355225578

Therefore, the lowest common multiple of 618,994,949,557 is 162355225578.

LCM Formula to Find Lowest Common Multiple of 618,994,949,557

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 994 x 949 x 557 = 324710451156

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

994 : 1, 2, 7, 14, 71, 142, 497, 994

949 : 1, 13, 73, 949

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,994,949,557, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

994:2x 7x 71

949:13x 73

557:557

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

2 = 2

Therefore, the value for common factors is 2.

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 = 324710451156/(1x2)

LCM = 324710451156/2

LCM = 162355225578

Thus, we can understand that the LCM of 618,994,949,557 is 162355225578.
