Given numbers are 121,457,247,169,727

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

The LCM of 121,457,247,169,727 is 129085150909.

Find LCM of 121,457,247,169,727 with Prime Factorization

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

13 x 121 x 457 x 19 x 13 x 727 = 129085150909

Therefore, the lowest common multiple of 121,457,247,169,727 is 129085150909.

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.

121 x 457 x 247 x 169 x 727 = 1678106961817

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.

121 : 1, 11, 121

457 : 1, 457

247 : 1, 13, 19, 247

169 : 1, 13, 169

727 : 1, 727

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,457,247,169,727, is 1.

Now, the common factors can be found like this.

121:11x 11

457:457

247:13x 19

169:13x 13

727:727

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

13 = 13

Therefore, the value for common factors is 13.

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 = 1678106961817/(1x13)

LCM = 1678106961817/13

LCM = 129085150909

Thus, we can understand that the LCM of 121,457,247,169,727 is 129085150909.
