Given numbers are 878,720,705,471

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

The LCM of 878,720,705,471 is 2332354320.

Find LCM of 878,720,705,471 with Prime Factorization

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

2 x 3 x 5 x 439 x 24 x 47 x 157 = 2332354320

Therefore, the lowest common multiple of 878,720,705,471 is 2332354320.

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.

878 x 720 x 705 x 471 = 209911888800

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.

878 : 1, 2, 439, 878

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

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

471 : 1, 3, 157, 471

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,720,705,471, is 1.

Now, the common factors can be found like this.

878:2x 439

720:2x 2x 2x 2x 3x 3x 5

705:3x 5x 47

471:3x 157

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

2x 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 209911888800/(1x90)

LCM = 209911888800/90

LCM = 2332354320

Thus, we can understand that the LCM of 878,720,705,471 is 2332354320.
