Given numbers are 991,460,492,380,856

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

The LCM of 991,460,492,380,856 is 227983791480.

Find LCM of 991,460,492,380,856 with Prime Factorization

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

2 x 2 x 5 x 991 x 23 x 123 x 19 x 214 = 227983791480

Therefore, the lowest common multiple of 991,460,492,380,856 is 227983791480.

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.

991 x 460 x 492 x 380 x 856 = 72954813273600

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.

991 : 1, 991

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,460,492,380,856, is 1.

Now, the common factors can be found like this.

991:991

460:2x 2x 5x 23

492:2x 2x 3x 41

380:2x 2x 5x 19

856:2x 2x 2x 107

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 2x 2x 2x 2x 5 = 320

Therefore, the value for common factors is 320.

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 = 72954813273600/(1x320)

LCM = 72954813273600/320

LCM = 227983791480

Thus, we can understand that the LCM of 991,460,492,380,856 is 227983791480.
