Given numbers are 648,421,166,680

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

The LCM of 648,421,166,680 is 1924660440.

Find LCM of 648,421,166,680 with Prime Factorization

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

2 x 2 x 2 x 81 x 421 x 83 x 85 = 1924660440

Therefore, the lowest common multiple of 648,421,166,680 is 1924660440.

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.

648 x 421 x 166 x 680 = 30794567040

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

421 : 1, 421

166 : 1, 2, 83, 166

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,421,166,680, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

421:421

166:2x 83

680:2x 2x 2x 5x 17

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 = 30794567040/(1x16)

LCM = 30794567040/16

LCM = 1924660440

Thus, we can understand that the LCM of 648,421,166,680 is 1924660440.
