Given numbers are 677,397,729,447,780

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

The LCM of 677,397,729,447,780 is 7590428962740.

Find LCM of 677,397,729,447,780 with Prime Factorization

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

3 x 677 x 397 x 243 x 149 x 260 = 7590428962740

Therefore, the lowest common multiple of 677,397,729,447,780 is 7590428962740.

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.

677 x 397 x 729 x 447 x 780 = 68313860664660

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.

677 : 1, 677

397 : 1, 397

729 : 1, 3, 9, 27, 81, 243, 729

447 : 1, 3, 149, 447

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,397,729,447,780, is 1.

Now, the common factors can be found like this.

677:677

397:397

729:3x 3x 3x 3x 3x 3

447:3x 149

780:2x 2x 3x 5x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 68313860664660/(1x9)

LCM = 68313860664660/9

LCM = 7590428962740

Thus, we can understand that the LCM of 677,397,729,447,780 is 7590428962740.
