Given numbers are 291,920,331,340

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

The LCM of 291,920,331,340 is 1506460440.

Find LCM of 291,920,331,340 with Prime Factorization

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

2 x 2 x 5 x 291 x 46 x 331 x 17 = 1506460440

Therefore, the lowest common multiple of 291,920,331,340 is 1506460440.

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.

291 x 920 x 331 x 340 = 30129208800

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.

291 : 1, 3, 97, 291

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

331 : 1, 331

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,920,331,340, is 1.

Now, the common factors can be found like this.

291:3x 97

920:2x 2x 2x 5x 23

331:331

340:2x 2x 5x 17

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 = 30129208800/(1x20)

LCM = 30129208800/20

LCM = 1506460440

Thus, we can understand that the LCM of 291,920,331,340 is 1506460440.
