Calculate the LCM of 991,677,862,680

Given numbers are 991,677,862,680

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

The LCM of 991,677,862,680 is 196629423560.

Find LCM of 991,677,862,680 with Prime Factorization


2 991, 677, 862, 680
991, 677, 431, 340

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

2 x 991 x 677 x 431 x 340 = 196629423560

Therefore, the lowest common multiple of 991,677,862,680 is 196629423560.

LCM Formula to Find Lowest Common Multiple of 991,677,862,680

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 677 x 862 x 680 = 393258847120

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

677 : 1, 677

862 : 1, 2, 431, 862

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,677,862,680, is 1.

Now, the common factors can be found like this.

991:991

677:677

862:2x 431

680:2x 2x 2x 5x 17

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 = 393258847120/(1x2)

LCM = 393258847120/2

LCM = 196629423560

Thus, we can understand that the LCM of 991,677,862,680 is 196629423560.
