Given numbers are 121,689,145,726

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

The LCM of 121,689,145,726 is 72531030.

Find LCM of 121,689,145,726 with Prime Factorization

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

11 x 11 x 1 x 689 x 145 x 6 = 72531030

Therefore, the lowest common multiple of 121,689,145,726 is 72531030.

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 689 x 145 x 726 = 8776254630

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

689 : 1, 13, 53, 689

145 : 1, 5, 29, 145

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,689,145,726, is 1.

Now, the common factors can be found like this.

121:11x 11

689:13x 53

145:5x 29

726:2x 3x 11x 11

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 8776254630/(1x121)

LCM = 8776254630/121

LCM = 72531030

Thus, we can understand that the LCM of 121,689,145,726 is 72531030.
