Given numbers are 668,727,646,210

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

The LCM of 668,727,646,210 is 16470344940.

Find LCM of 668,727,646,210 with Prime Factorization

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

2 x 334 x 727 x 323 x 105 = 16470344940

Therefore, the lowest common multiple of 668,727,646,210 is 16470344940.

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.

668 x 727 x 646 x 210 = 65881379760

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.

668 : 1, 2, 4, 167, 334, 668

727 : 1, 727

646 : 1, 2, 17, 19, 34, 38, 323, 646

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,727,646,210, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

727:727

646:2x 17x 19

210:2x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 65881379760/(1x4)

LCM = 65881379760/4

LCM = 16470344940

Thus, we can understand that the LCM of 668,727,646,210 is 16470344940.
