Given numbers are 654,565,621,566

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

The LCM of 654,565,621,566 is 21646265310.

Find LCM of 654,565,621,566 with Prime Factorization

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

2 x 3 x 109 x 565 x 207 x 283 = 21646265310

Therefore, the lowest common multiple of 654,565,621,566 is 21646265310.

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.

654 x 565 x 621 x 566 = 129877591860

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

565 : 1, 5, 113, 565

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

566 : 1, 2, 283, 566

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,565,621,566, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

565:5x 113

621:3x 3x 3x 23

566:2x 283

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 129877591860/(1x6)

LCM = 129877591860/6

LCM = 21646265310

Thus, we can understand that the LCM of 654,565,621,566 is 21646265310.
