Given numbers are 720,747,722,612

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

The LCM of 720,747,722,612 is 366747120.

Find LCM of 720,747,722,612 with Prime Factorization

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

2 x 2 x 3 x 3 x 20 x 83 x 361 x 17 = 366747120

Therefore, the lowest common multiple of 720,747,722,612 is 366747120.

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 747 x 722 x 612 = 237652133760

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

747 : 1, 3, 9, 83, 249, 747

722 : 1, 2, 19, 38, 361, 722

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,747,722,612, is 1.

Now, the common factors can be found like this.

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

747:3x 3x 83

722:2x 19x 19

612:2x 2x 3x 3x 17

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 3x 3x 3 = 648

Therefore, the value for common factors is 648.

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 = 237652133760/(1x648)

LCM = 237652133760/648

LCM = 366747120

Thus, we can understand that the LCM of 720,747,722,612 is 366747120.
