Given numbers are 281,160,910,646

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

The LCM of 281,160,910,646 is 1321509280.

Find LCM of 281,160,910,646 with Prime Factorization

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

2 x 5 x 281 x 16 x 91 x 323 = 1321509280

Therefore, the lowest common multiple of 281,160,910,646 is 1321509280.

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 160 x 910 x 646 = 26430185600

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

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,160,910,646, is 1.

Now, the common factors can be found like this.

281:281

160:2x 2x 2x 2x 2x 5

910:2x 5x 7x 13

646:2x 17x 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 5 = 20

Therefore, the value for common factors is 20.

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 = 26430185600/(1x20)

LCM = 26430185600/20

LCM = 1321509280

Thus, we can understand that the LCM of 281,160,910,646 is 1321509280.
