Given numbers are 121,554,736,487,840

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

The LCM of 121,554,736,487,840 is 1261424361120.

Find LCM of 121,554,736,487,840 with Prime Factorization

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

2 x 2 x 2 x 121 x 277 x 92 x 487 x 105 = 1261424361120

Therefore, the lowest common multiple of 121,554,736,487,840 is 1261424361120.

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 554 x 736 x 487 x 840 = 20182789777920

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

554 : 1, 2, 277, 554

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

487 : 1, 487

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,554,736,487,840, is 1.

Now, the common factors can be found like this.

121:11x 11

554:2x 277

736:2x 2x 2x 2x 2x 23

487:487

840:2x 2x 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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 20182789777920/(1x16)

LCM = 20182789777920/16

LCM = 1261424361120

Thus, we can understand that the LCM of 121,554,736,487,840 is 1261424361120.
