Given numbers are 717,349,140,621

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

The LCM of 717,349,140,621 is 7251752340.

Find LCM of 717,349,140,621 with Prime Factorization

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

3 x 239 x 349 x 140 x 207 = 7251752340

Therefore, the lowest common multiple of 717,349,140,621 is 7251752340.

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.

717 x 349 x 140 x 621 = 21755257020

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.

717 : 1, 3, 239, 717

349 : 1, 349

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,349,140,621, is 1.

Now, the common factors can be found like this.

717:3x 239

349:349

140:2x 2x 5x 7

621:3x 3x 3x 23

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

3 = 3

Therefore, the value for common factors is 3.

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 = 21755257020/(1x3)

LCM = 21755257020/3

LCM = 7251752340

Thus, we can understand that the LCM of 717,349,140,621 is 7251752340.
