Given numbers are 216,991,218,370

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

The LCM of 216,991,218,370 is 4316439240.

Find LCM of 216,991,218,370 with Prime Factorization

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

2 x 108 x 991 x 109 x 185 = 4316439240

Therefore, the lowest common multiple of 216,991,218,370 is 4316439240.

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 991 x 218 x 370 = 17265756960

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

991 : 1, 991

218 : 1, 2, 109, 218

370 : 1, 2, 5, 10, 37, 74, 185, 370

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,991,218,370, is 1.

Now, the common factors can be found like this.

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

991:991

218:2x 109

370:2x 5x 37

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 17265756960/(1x4)

LCM = 17265756960/4

LCM = 4316439240

Thus, we can understand that the LCM of 216,991,218,370 is 4316439240.
