Given numbers are 657,291,716,621

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

The LCM of 657,291,716,621 is 3148467516.

Find LCM of 657,291,716,621 with Prime Factorization

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

3 x 3 x 73 x 97 x 716 x 69 = 3148467516

Therefore, the lowest common multiple of 657,291,716,621 is 3148467516.

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.

657 x 291 x 716 x 621 = 85008622932

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.

657 : 1, 3, 9, 73, 219, 657

291 : 1, 3, 97, 291

716 : 1, 2, 4, 179, 358, 716

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 657,291,716,621, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

291:3x 97

716:2x 2x 179

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.

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 85008622932/(1x27)

LCM = 85008622932/27

LCM = 3148467516

Thus, we can understand that the LCM of 657,291,716,621 is 3148467516.
