Calculate the LCM of 218,421,321,396,671

Given numbers are 218,421,321,396,671

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

The LCM of 218,421,321,396,671 is 118608931188.

Find LCM of 218,421,321,396,671 with Prime Factorization


2 218, 421, 321, 396, 671
3 109, 421, 321, 198, 671
11 109, 421, 107, 66, 671
109, 421, 107, 6, 61

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

2 x 3 x 11 x 109 x 421 x 107 x 6 x 61 = 118608931188

Therefore, the lowest common multiple of 218,421,321,396,671 is 118608931188.

LCM Formula to Find Lowest Common Multiple of 218,421,321,396,671

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 421 x 321 x 396 x 671 = 7828189458408

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

421 : 1, 421

321 : 1, 3, 107, 321

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,421,321,396,671, is 1.

Now, the common factors can be found like this.

218:2x 109

421:421

321:3x 107

396:2x 2x 3x 3x 11

671:11x 61

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

2x 3x 11 = 66

Therefore, the value for common factors is 66.

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 = 7828189458408/(1x66)

LCM = 7828189458408/66

LCM = 118608931188

Thus, we can understand that the LCM of 218,421,321,396,671 is 118608931188.
