Given numbers are 418,340,220,163,716

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

The LCM of 418,340,220,163,716 is 2073317620.

Find LCM of 418,340,220,163,716 with Prime Factorization

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

2 x 2 x 5 x 11 x 19 x 17 x 1 x 163 x 179 = 2073317620

Therefore, the lowest common multiple of 418,340,220,163,716 is 2073317620.

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.

418 x 340 x 220 x 163 x 716 = 3649039011200

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.

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

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

163 : 1, 163

716 : 1, 2, 4, 179, 358, 716

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,340,220,163,716, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

340:2x 2x 5x 17

220:2x 2x 5x 11

163:163

716:2x 2x 179

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 2x 2x 2x 5x 11 = 1760

Therefore, the value for common factors is 1760.

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 = 3649039011200/(1x1760)

LCM = 3649039011200/1760

LCM = 2073317620

Thus, we can understand that the LCM of 418,340,220,163,716 is 2073317620.
