Given numbers are 780,775,191,115,520

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

The LCM of 780,775,191,115,520 is 1062227400.

Find LCM of 780,775,191,115,520 with Prime Factorization

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

2 x 2 x 5 x 13 x 3 x 155 x 191 x 23 x 2 = 1062227400

Therefore, the lowest common multiple of 780,775,191,115,520 is 1062227400.

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 775 x 191 x 115 x 520 = 6904478100000

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

775 : 1, 5, 25, 31, 155, 775

191 : 1, 191

115 : 1, 5, 23, 115

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,775,191,115,520, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

775:5x 5x 31

191:191

115:5x 23

520:2x 2x 2x 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.

2x 2x 5x 5x 5x 13 = 6500

Therefore, the value for common factors is 6500.

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 = 6904478100000/(1x6500)

LCM = 6904478100000/6500

LCM = 1062227400

Thus, we can understand that the LCM of 780,775,191,115,520 is 1062227400.
