Calculate the LCM of 216,860,665,995

Given numbers are 216,860,665,995

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

The LCM of 216,860,665,995 is 1229127480.

Find LCM of 216,860,665,995 with Prime Factorization


2 216, 860, 665, 995
2 108, 430, 665, 995
5 54, 215, 665, 995
54, 43, 133, 199

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

2 x 2 x 5 x 54 x 43 x 133 x 199 = 1229127480

Therefore, the lowest common multiple of 216,860,665,995 is 1229127480.

LCM Formula to Find Lowest Common Multiple of 216,860,665,995

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.

216 x 860 x 665 x 995 = 122912748000

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.

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

665 : 1, 5, 7, 19, 35, 95, 133, 665

995 : 1, 5, 199, 995

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,860,665,995, is 1.

Now, the common factors can be found like this.

216:2x 2x 2x 3x 3x 3

860:2x 2x 5x 43

665:5x 7x 19

995:5x 199

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

2x 2x 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 122912748000/(1x100)

LCM = 122912748000/100

LCM = 1229127480

Thus, we can understand that the LCM of 216,860,665,995 is 1229127480.
