Given numbers are 207,912,780,447

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

The LCM of 207,912,780,447 is 609457680.

Find LCM of 207,912,780,447 with Prime Factorization

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

2 x 2 x 3 x 69 x 76 x 65 x 149 = 609457680

Therefore, the lowest common multiple of 207,912,780,447 is 609457680.

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.

207 x 912 x 780 x 447 = 65821429440

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.

207 : 1, 3, 9, 23, 69, 207

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

447 : 1, 3, 149, 447

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,912,780,447, is 3.

Now, the common factors can be found like this.

207:3x 3x 23

912:2x 2x 2x 2x 3x 19

780:2x 2x 3x 5x 13

447:3x 149

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 3 = 36

Therefore, the value for common factors is 36.

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 = 65821429440/(3x36)

LCM = 65821429440/108

LCM = 609457680

Thus, we can understand that the LCM of 207,912,780,447 is 609457680.
