Given numbers are 720,767,910,660

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

The LCM of 720,767,910,660 is 42522480.

Find LCM of 720,767,910,660 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 12 x 59 x 7 x 11 = 42522480

Therefore, the lowest common multiple of 720,767,910,660 is 42522480.

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.

720 x 767 x 910 x 660 = 331675344000

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.

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

767 : 1, 13, 59, 767

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,767,910,660, is 1.

Now, the common factors can be found like this.

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

767:13x 59

910:2x 5x 7x 13

660:2x 2x 3x 5x 11

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 3x 5x 5x 13 = 7800

Therefore, the value for common factors is 7800.

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 = 331675344000/(1x7800)

LCM = 331675344000/7800

LCM = 42522480

Thus, we can understand that the LCM of 720,767,910,660 is 42522480.
