Given numbers are 720,551,702,613

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

The LCM of 720,551,702,613 is 9484385040.

Find LCM of 720,551,702,613 with Prime Factorization

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

2 x 3 x 3 x 40 x 551 x 39 x 613 = 9484385040

Therefore, the lowest common multiple of 720,551,702,613 is 9484385040.

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 551 x 702 x 613 = 170718930720

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

551 : 1, 19, 29, 551

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

613 : 1, 613

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,551,702,613, is 1.

Now, the common factors can be found like this.

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

551:19x 29

702:2x 3x 3x 3x 13

613:613

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 3 = 18

Therefore, the value for common factors is 18.

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 = 170718930720/(1x18)

LCM = 170718930720/18

LCM = 9484385040

Thus, we can understand that the LCM of 720,551,702,613 is 9484385040.
