Given numbers are 247,642,687,726,210

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

The LCM of 247,642,687,726,210 is 153787443810.

Find LCM of 247,642,687,726,210 with Prime Factorization

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

2 x 3 x 247 x 107 x 229 x 121 x 35 = 153787443810

Therefore, the lowest common multiple of 247,642,687,726,210 is 153787443810.

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.

247 x 642 x 687 x 726 x 210 = 16609043931480

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.

247 : 1, 13, 19, 247

642 : 1, 2, 3, 6, 107, 214, 321, 642

687 : 1, 3, 229, 687

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,642,687,726,210, is 1.

Now, the common factors can be found like this.

247:13x 19

642:2x 3x 107

687:3x 229

726:2x 3x 11x 11

210:2x 3x 5x 7

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 16609043931480/(1x108)

LCM = 16609043931480/108

LCM = 153787443810

Thus, we can understand that the LCM of 247,642,687,726,210 is 153787443810.
