Given numbers are 705,491,665,940

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

The LCM of 705,491,665,940 is 184154460.

Find LCM of 705,491,665,940 with Prime Factorization

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

5 x 47 x 3 x 491 x 133 x 4 = 184154460

Therefore, the lowest common multiple of 705,491,665,940 is 184154460.

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.

705 x 491 x 665 x 940 = 216381490500

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

491 : 1, 491

665 : 1, 5, 7, 19, 35, 95, 133, 665

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,491,665,940, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

491:491

665:5x 7x 19

940:2x 2x 5x 47

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

5x 5x 47 = 1175

Therefore, the value for common factors is 1175.

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 = 216381490500/(1x1175)

LCM = 216381490500/1175

LCM = 184154460

Thus, we can understand that the LCM of 705,491,665,940 is 184154460.
