Given numbers are 660,724,473,880

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

The LCM of 660,724,473,880 is 20547120.

Find LCM of 660,724,473,880 with Prime Factorization

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

2 x 2 x 5 x 11 x 3 x 181 x 43 x 4 = 20547120

Therefore, the lowest common multiple of 660,724,473,880 is 20547120.

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.

660 x 724 x 473 x 880 = 198896121600

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.

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

724 : 1, 2, 4, 181, 362, 724

473 : 1, 11, 43, 473

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,724,473,880, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

724:2x 2x 181

473:11x 43

880:2x 2x 2x 2x 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 2x 5x 11x 11 = 9680

Therefore, the value for common factors is 9680.

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 = 198896121600/(1x9680)

LCM = 198896121600/9680

LCM = 20547120

Thus, we can understand that the LCM of 660,724,473,880 is 20547120.
