Given numbers are 991,687,898,960

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

The LCM of 991,687,898,960 is 97819786560.

Find LCM of 991,687,898,960 with Prime Factorization


2 991, 687, 898, 960
3 991, 687, 449, 480
991, 229, 449, 160

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

2 x 3 x 991 x 229 x 449 x 160 = 97819786560

Therefore, the lowest common multiple of 991,687,898,960 is 97819786560.

LCM Formula to Find Lowest Common Multiple of 991,687,898,960

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 687 x 898 x 960 = 586918719360

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

687 : 1, 3, 229, 687

898 : 1, 2, 449, 898

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,687,898,960, is 1.

Now, the common factors can be found like this.

991:991

687:3x 229

898:2x 449

960:2x 2x 2x 2x 2x 2x 3x 5

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 586918719360/(1x6)

LCM = 586918719360/6

LCM = 97819786560

Thus, we can understand that the LCM of 991,687,898,960 is 97819786560.
