Given numbers are 621,393,216,540,283

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

The LCM of 621,393,216,540,283 is 920893320.

Find LCM of 621,393,216,540,283 with Prime Factorization

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

2 x 2 x 3 x 3 x 3 x 23 x 131 x 2 x 5 x 283 = 920893320

Therefore, the lowest common multiple of 621,393,216,540,283 is 920893320.

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.

621 x 393 x 216 x 540 x 283 = 8055974763360

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.

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

393 : 1, 3, 131, 393

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

283 : 1, 283

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,393,216,540,283, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

393:3x 131

216:2x 2x 2x 3x 3x 3

540:2x 2x 3x 3x 3x 5

283:283

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

2x 2x 3x 3x 3x 3x 3x 3x 3 = 8748

Therefore, the value for common factors is 8748.

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 = 8055974763360/(1x8748)

LCM = 8055974763360/8748

LCM = 920893320

Thus, we can understand that the LCM of 621,393,216,540,283 is 920893320.
