Given numbers are 217,115,671,814

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

The LCM of 217,115,671,814 is 1239115570.

Find LCM of 217,115,671,814 with Prime Factorization

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

11 x 217 x 115 x 61 x 74 = 1239115570

Therefore, the lowest common multiple of 217,115,671,814 is 1239115570.

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.

217 x 115 x 671 x 814 = 13630271270

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.

217 : 1, 7, 31, 217

115 : 1, 5, 23, 115

671 : 1, 11, 61, 671

814 : 1, 2, 11, 22, 37, 74, 407, 814

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,115,671,814, is 1.

Now, the common factors can be found like this.

217:7x 31

115:5x 23

671:11x 61

814:2x 11x 37

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

11 = 11

Therefore, the value for common factors is 11.

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 = 13630271270/(1x11)

LCM = 13630271270/11

LCM = 1239115570

Thus, we can understand that the LCM of 217,115,671,814 is 1239115570.
