Given numbers are 281,356,720,494

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

The LCM of 281,356,720,494 is 4447600560.

Find LCM of 281,356,720,494 with Prime Factorization

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

2 x 2 x 281 x 89 x 180 x 247 = 4447600560

Therefore, the lowest common multiple of 281,356,720,494 is 4447600560.

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.

281 x 356 x 720 x 494 = 35580804480

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.

281 : 1, 281

356 : 1, 2, 4, 89, 178, 356

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,356,720,494, is 1.

Now, the common factors can be found like this.

281:281

356:2x 2x 89

720:2x 2x 2x 2x 3x 3x 5

494:2x 13x 19

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 2 = 8

Therefore, the value for common factors is 8.

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 = 35580804480/(1x8)

LCM = 35580804480/8

LCM = 4447600560

Thus, we can understand that the LCM of 281,356,720,494 is 4447600560.
