Given numbers are 636,143,455,217

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

The LCM of 636,143,455,217 is 98678580.

Find LCM of 636,143,455,217 with Prime Factorization

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

7 x 13 x 636 x 11 x 5 x 31 = 98678580

Therefore, the lowest common multiple of 636,143,455,217 is 98678580.

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.

636 x 143 x 455 x 217 = 8979750780

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

143 : 1, 11, 13, 143

455 : 1, 5, 7, 13, 35, 65, 91, 455

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,143,455,217, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

143:11x 13

455:5x 7x 13

217:7x 31

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

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 8979750780/(1x91)

LCM = 8979750780/91

LCM = 98678580

Thus, we can understand that the LCM of 636,143,455,217 is 98678580.
