Calculate the LCM of 100,561,894,957

Given numbers are 100,561,894,957

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

The LCM of 100,561,894,957 is 242408100.

Find LCM of 100,561,894,957 with Prime Factorization


2 100, 561, 894, 957
3 50, 561, 447, 957
11 50, 187, 149, 319
50, 17, 149, 29

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

2 x 3 x 11 x 50 x 17 x 149 x 29 = 242408100

Therefore, the lowest common multiple of 100,561,894,957 is 242408100.

LCM Formula to Find Lowest Common Multiple of 100,561,894,957

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.

100 x 561 x 894 x 957 = 47996803800

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.

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

561 : 1, 3, 11, 17, 33, 51, 187, 561

894 : 1, 2, 3, 6, 149, 298, 447, 894

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,561,894,957, is 1.

Now, the common factors can be found like this.

100:2x 2x 5x 5

561:3x 11x 17

894:2x 3x 149

957:3x 11x 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 3x 3x 11 = 198

Therefore, the value for common factors is 198.

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 = 47996803800/(1x198)

LCM = 47996803800/198

LCM = 242408100

Thus, we can understand that the LCM of 100,561,894,957 is 242408100.
