Given numbers are 780,798,494,878

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

The LCM of 780,798,494,878 is 45541860.

Find LCM of 780,798,494,878 with Prime Factorization

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

2 x 3 x 13 x 19 x 10 x 7 x 1 x 439 = 45541860

Therefore, the lowest common multiple of 780,798,494,878 is 45541860.

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 798 x 494 x 878 = 269972146080

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

494 : 1, 2, 13, 19, 26, 38, 247, 494

878 : 1, 2, 439, 878

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,798,494,878, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

798:2x 3x 7x 19

494:2x 13x 19

878:2x 439

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 13x 19 = 2964

Therefore, the value for common factors is 2964.

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 = 269972146080/(2x2964)

LCM = 269972146080/5928

LCM = 45541860

Thus, we can understand that the LCM of 780,798,494,878 is 45541860.
