Given numbers are 391,187,473,748

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

The LCM of 391,187,473,748 is 739772.

Find LCM of 391,187,473,748 with Prime Factorization

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

11 x 17 x 23 x 1 x 43 x 4 = 739772

Therefore, the lowest common multiple of 391,187,473,748 is 739772.

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.

391 x 187 x 473 x 748 = 25869087068

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.

391 : 1, 17, 23, 391

187 : 1, 11, 17, 187

473 : 1, 11, 43, 473

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,187,473,748, is 1.

Now, the common factors can be found like this.

391:17x 23

187:11x 17

473:11x 43

748:2x 2x 11x 17

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

11x 11x 17x 17 = 34969

Therefore, the value for common factors is 34969.

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 = 25869087068/(1x34969)

LCM = 25869087068/34969

LCM = 739772

Thus, we can understand that the LCM of 391,187,473,748 is 739772.
