Given numbers are 218,435,357,985

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

The LCM of 218,435,357,985 is 2223099690.

Find LCM of 218,435,357,985 with Prime Factorization

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

3 x 5 x 218 x 29 x 119 x 197 = 2223099690

Therefore, the lowest common multiple of 218,435,357,985 is 2223099690.

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.

218 x 435 x 357 x 985 = 33346495350

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.

218 : 1, 2, 109, 218

435 : 1, 3, 5, 15, 29, 87, 145, 435

357 : 1, 3, 7, 17, 21, 51, 119, 357

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,435,357,985, is 1.

Now, the common factors can be found like this.

218:2x 109

435:3x 5x 29

357:3x 7x 17

985:5x 197

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 33346495350/(1x15)

LCM = 33346495350/15

LCM = 2223099690

Thus, we can understand that the LCM of 218,435,357,985 is 2223099690.
