Given numbers are 212,991,388,785

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

The LCM of 212,991,388,785 is 15997455340.

Find LCM of 212,991,388,785 with Prime Factorization

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

2 x 2 x 53 x 991 x 97 x 785 = 15997455340

Therefore, the lowest common multiple of 212,991,388,785 is 15997455340.

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.

212 x 991 x 388 x 785 = 63989821360

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.

212 : 1, 2, 4, 53, 106, 212

991 : 1, 991

388 : 1, 2, 4, 97, 194, 388

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,991,388,785, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

991:991

388:2x 2x 97

785:5x 157

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 = 63989821360/(1x4)

LCM = 63989821360/4

LCM = 15997455340

Thus, we can understand that the LCM of 212,991,388,785 is 15997455340.
