Given numbers are 780,209,520,635,565

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

The LCM of 780,209,520,635,565 is 4679000040.

Find LCM of 780,209,520,635,565 with Prime Factorization

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

2 x 2 x 5 x 13 x 3 x 209 x 2 x 127 x 113 = 4679000040

Therefore, the lowest common multiple of 780,209,520,635,565 is 4679000040.

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 209 x 520 x 635 x 565 = 30413500260000

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

209 : 1, 11, 19, 209

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

635 : 1, 5, 127, 635

565 : 1, 5, 113, 565

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,209,520,635,565, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

209:11x 19

520:2x 2x 2x 5x 13

635:5x 127

565:5x 113

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 = 30413500260000/(1x6500)

LCM = 30413500260000/6500

LCM = 4679000040

Thus, we can understand that the LCM of 780,209,520,635,565 is 4679000040.
