Calculate the LCM of 991,393,962,856

Given numbers are 991,393,962,856

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

The LCM of 991,393,962,856 is 160355937768.

Find LCM of 991,393,962,856 with Prime Factorization


2 991, 393, 962, 856
991, 393, 481, 428

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

2 x 991 x 393 x 481 x 428 = 160355937768

Therefore, the lowest common multiple of 991,393,962,856 is 160355937768.

LCM Formula to Find Lowest Common Multiple of 991,393,962,856

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 393 x 962 x 856 = 320711875536

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

393 : 1, 3, 131, 393

962 : 1, 2, 13, 26, 37, 74, 481, 962

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,393,962,856, is 1.

Now, the common factors can be found like this.

991:991

393:3x 131

962:2x 13x 37

856:2x 2x 2x 107

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 = 320711875536/(1x2)

LCM = 320711875536/2

LCM = 160355937768

Thus, we can understand that the LCM of 991,393,962,856 is 160355937768.
