Given numbers are 780,293,990,345

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

The LCM of 780,293,990,345 is 173461860.

Find LCM of 780,293,990,345 with Prime Factorization

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

2 x 3 x 5 x 26 x 293 x 33 x 23 = 173461860

Therefore, the lowest common multiple of 780,293,990,345 is 173461860.

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 293 x 990 x 345 = 78057837000

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

293 : 1, 293

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

345 : 1, 3, 5, 15, 23, 69, 115, 345

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,293,990,345, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

293:293

990:2x 3x 3x 5x 11

345:3x 5x 23

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

2x 3x 3x 5x 5 = 450

Therefore, the value for common factors is 450.

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 = 78057837000/(1x450)

LCM = 78057837000/450

LCM = 173461860

Thus, we can understand that the LCM of 780,293,990,345 is 173461860.
