Given numbers are 121,180,726,497,472

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

The LCM of 121,180,726,497,472 is 1277309880.

Find LCM of 121,180,726,497,472 with Prime Factorization

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

2 x 2 x 3 x 11 x 11 x 1 x 15 x 1 x 497 x 118 = 1277309880

Therefore, the lowest common multiple of 121,180,726,497,472 is 1277309880.

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 180 x 726 x 497 x 472 = 3709307891520

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

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

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

497 : 1, 7, 71, 497

472 : 1, 2, 4, 8, 59, 118, 236, 472

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,180,726,497,472, is 1.

Now, the common factors can be found like this.

121:11x 11

180:2x 2x 3x 3x 5

726:2x 3x 11x 11

497:7x 71

472:2x 2x 2x 59

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 2x 3x 11x 11 = 2904

Therefore, the value for common factors is 2904.

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 = 3709307891520/(1x2904)

LCM = 3709307891520/2904

LCM = 1277309880

Thus, we can understand that the LCM of 121,180,726,497,472 is 1277309880.
