Given numbers are 122,418,406,493

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

The LCM of 122,418,406,493 is 87993598.

Find LCM of 122,418,406,493 with Prime Factorization

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

2 x 29 x 61 x 209 x 7 x 17 = 87993598

Therefore, the lowest common multiple of 122,418,406,493 is 87993598.

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.

122 x 418 x 406 x 493 = 10207257368

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.

122 : 1, 2, 61, 122

418 : 1, 2, 11, 19, 22, 38, 209, 418

406 : 1, 2, 7, 14, 29, 58, 203, 406

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,418,406,493, is 1.

Now, the common factors can be found like this.

122:2x 61

418:2x 11x 19

406:2x 7x 29

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.

2x 2x 29 = 116

Therefore, the value for common factors is 116.

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 = 10207257368/(1x116)

LCM = 10207257368/116

LCM = 87993598

Thus, we can understand that the LCM of 122,418,406,493 is 87993598.
