Given numbers are 668,713,545,621

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

The LCM of 668,713,545,621 is 7008519060.

Find LCM of 668,713,545,621 with Prime Factorization

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

23 x 668 x 31 x 545 x 27 = 7008519060

Therefore, the lowest common multiple of 668,713,545,621 is 7008519060.

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 713 x 545 x 621 = 161195938380

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

713 : 1, 23, 31, 713

545 : 1, 5, 109, 545

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 668,713,545,621, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

713:23x 31

545:5x 109

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.

23 = 23

Therefore, the value for common factors is 23.

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 = 161195938380/(1x23)

LCM = 161195938380/23

LCM = 7008519060

Thus, we can understand that the LCM of 668,713,545,621 is 7008519060.
