Given numbers are 121,840,553,483,169

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

The LCM of 121,840,553,483,169 is 31210899720.

Find LCM of 121,840,553,483,169 with Prime Factorization

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

3 x 7 x 121 x 40 x 79 x 23 x 169 = 31210899720

Therefore, the lowest common multiple of 121,840,553,483,169 is 31210899720.

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 840 x 553 x 483 x 169 = 4588002258840

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

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

553 : 1, 7, 79, 553

483 : 1, 3, 7, 21, 23, 69, 161, 483

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,840,553,483,169, is 1.

Now, the common factors can be found like this.

121:11x 11

840:2x 2x 2x 3x 5x 7

553:7x 79

483:3x 7x 23

169:13x 13

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

3x 7x 7 = 147

Therefore, the value for common factors is 147.

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 = 4588002258840/(1x147)

LCM = 4588002258840/147

LCM = 31210899720

Thus, we can understand that the LCM of 121,840,553,483,169 is 31210899720.
