Given numbers are 215,661,187,493

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

The LCM of 215,661,187,493 is 770689645.

Find LCM of 215,661,187,493 with Prime Factorization

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

17 x 215 x 661 x 11 x 29 = 770689645

Therefore, the lowest common multiple of 215,661,187,493 is 770689645.

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.

215 x 661 x 187 x 493 = 13101723965

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.

215 : 1, 5, 43, 215

661 : 1, 661

187 : 1, 11, 17, 187

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,661,187,493, is 1.

Now, the common factors can be found like this.

215:5x 43

661:661

187:11x 17

493:17x 29

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

17 = 17

Therefore, the value for common factors is 17.

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 = 13101723965/(1x17)

LCM = 13101723965/17

LCM = 770689645

Thus, we can understand that the LCM of 215,661,187,493 is 770689645.
