Given numbers are 807,287,761,817,720

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

The LCM of 807,287,761,817,720 is 34559972359920.

Find LCM of 807,287,761,817,720 with Prime Factorization

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

3 x 269 x 287 x 761 x 817 x 240 = 34559972359920

Therefore, the lowest common multiple of 807,287,761,817,720 is 34559972359920.

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.

807 x 287 x 761 x 817 x 720 = 103679917079760

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.

807 : 1, 3, 269, 807

287 : 1, 7, 41, 287

761 : 1, 761

817 : 1, 19, 43, 817

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 807,287,761,817,720, is 1.

Now, the common factors can be found like this.

807:3x 269

287:7x 41

761:761

817:19x 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.

3 = 3

Therefore, the value for common factors is 3.

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 = 103679917079760/(1x3)

LCM = 103679917079760/3

LCM = 34559972359920

Thus, we can understand that the LCM of 807,287,761,817,720 is 34559972359920.
