Given numbers are 103,451,687,660,720

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

The LCM of 103,451,687,660,720 is 7659170640.

Find LCM of 103,451,687,660,720 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 103 x 41 x 229 x 1 x 12 = 7659170640

Therefore, the lowest common multiple of 103,451,687,660,720 is 7659170640.

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.

103 x 451 x 687 x 660 x 720 = 15165157867200

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.

103 : 1, 103

451 : 1, 11, 41, 451

687 : 1, 3, 229, 687

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

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 103,451,687,660,720, is 1.

Now, the common factors can be found like this.

103:103

451:11x 41

687:3x 229

660:2x 2x 3x 5x 11

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 3x 3x 5x 11 = 1980

Therefore, the value for common factors is 1980.

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 = 15165157867200/(1x1980)

LCM = 15165157867200/1980

LCM = 7659170640

Thus, we can understand that the LCM of 103,451,687,660,720 is 7659170640.
