Given numbers are 663,621,681,454

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

The LCM of 663,621,681,454 is 62307414.

Find LCM of 663,621,681,454 with Prime Factorization

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

3 x 227 x 221 x 207 x 1 x 2 = 62307414

Therefore, the lowest common multiple of 663,621,681,454 is 62307414.

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.

663 x 621 x 681 x 454 = 127294046802

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

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

681 : 1, 3, 227, 681

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,621,681,454, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

621:3x 3x 3x 23

681:3x 227

454:2x 227

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 227 = 2043

Therefore, the value for common factors is 2043.

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 = 127294046802/(1x2043)

LCM = 127294046802/2043

LCM = 62307414

Thus, we can understand that the LCM of 663,621,681,454 is 62307414.
