Given numbers are 780,728,277,740,854

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

The LCM of 780,728,277,740,854 is 6827063880.

Find LCM of 780,728,277,740,854 with Prime Factorization

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

2 x 2 x 5 x 7 x 13 x 3 x 2 x 277 x 37 x 61 = 6827063880

Therefore, the lowest common multiple of 780,728,277,740,854 is 6827063880.

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.

780 x 728 x 277 x 740 x 854 = 99402050092800

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.

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

277 : 1, 277

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,728,277,740,854, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

728:2x 2x 2x 7x 13

277:277

740:2x 2x 5x 37

854:2x 7x 61

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 2x 5x 7x 13 = 14560

Therefore, the value for common factors is 14560.

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 = 99402050092800/(1x14560)

LCM = 99402050092800/14560

LCM = 6827063880

Thus, we can understand that the LCM of 780,728,277,740,854 is 6827063880.
