Given numbers are 963,642,215,163

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

The LCM of 963,642,215,163 is 67496670.

Find LCM of 963,642,215,163 with Prime Factorization

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

3 x 107 x 3 x 2 x 215 x 163 = 67496670

Therefore, the lowest common multiple of 963,642,215,163 is 67496670.

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.

963 x 642 x 215 x 163 = 21666431070

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.

963 : 1, 3, 9, 107, 321, 963

642 : 1, 2, 3, 6, 107, 214, 321, 642

215 : 1, 5, 43, 215

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,642,215,163, is 1.

Now, the common factors can be found like this.

963:3x 3x 107

642:2x 3x 107

215:5x 43

163:163

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

3x 107 = 321

Therefore, the value for common factors is 321.

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 = 21666431070/(1x321)

LCM = 21666431070/321

LCM = 67496670

Thus, we can understand that the LCM of 963,642,215,163 is 67496670.
