Given numbers are 387,936,654,980,161

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

The LCM of 387,936,654,980,161 is 24720925320.

Find LCM of 387,936,654,980,161 with Prime Factorization

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

2 x 2 x 3 x 3 x 7 x 43 x 26 x 109 x 35 x 23 = 24720925320

Therefore, the lowest common multiple of 387,936,654,980,161 is 24720925320.

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.

387 x 936 x 654 x 980 x 161 = 37378039083840

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.

387 : 1, 3, 9, 43, 129, 387

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

654 : 1, 2, 3, 6, 109, 218, 327, 654

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,936,654,980,161, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

936:2x 2x 2x 3x 3x 13

654:2x 3x 109

980:2x 2x 5x 7x 7

161:7x 23

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 3x 3x 7 = 1512

Therefore, the value for common factors is 1512.

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 = 37378039083840/(1x1512)

LCM = 37378039083840/1512

LCM = 24720925320

Thus, we can understand that the LCM of 387,936,654,980,161 is 24720925320.
