Given numbers are 817,688,235,473,720

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

The LCM of 817,688,235,473,720 is 304120080.

Find LCM of 817,688,235,473,720 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 43 x 19 x 1 x 47 x 11 x 9 = 304120080

Therefore, the lowest common multiple of 817,688,235,473,720 is 304120080.

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.

817 x 688 x 235 x 473 x 720 = 44985442233600

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.

817 : 1, 19, 43, 817

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

235 : 1, 5, 47, 235

473 : 1, 11, 43, 473

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,688,235,473,720, is 1.

Now, the common factors can be found like this.

817:19x 43

688:2x 2x 2x 2x 43

235:5x 47

473:11x 43

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

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 5x 43x 43 = 147920

Therefore, the value for common factors is 147920.

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 = 44985442233600/(1x147920)

LCM = 44985442233600/147920

LCM = 304120080

Thus, we can understand that the LCM of 817,688,235,473,720 is 304120080.
