Calculate the LCM of 991,398,723,496

Given numbers are 991,398,723,496

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

The LCM of 991,398,723,496 is 70720725072.

Find LCM of 991,398,723,496 with Prime Factorization


2 991, 398, 723, 496
991, 199, 723, 248

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

2 x 991 x 199 x 723 x 248 = 70720725072

Therefore, the lowest common multiple of 991,398,723,496 is 70720725072.

LCM Formula to Find Lowest Common Multiple of 991,398,723,496

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.

991 x 398 x 723 x 496 = 141441450144

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.

991 : 1, 991

398 : 1, 2, 199, 398

723 : 1, 3, 241, 723

496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,398,723,496, is 1.

Now, the common factors can be found like this.

991:991

398:2x 199

723:3x 241

496:2x 2x 2x 2x 31

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 = 141441450144/(1x2)

LCM = 141441450144/2

LCM = 70720725072

Thus, we can understand that the LCM of 991,398,723,496 is 70720725072.
