Given numbers are 780,159,243,686,624

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

The LCM of 780,159,243,686,624 is 4594196880.

Find LCM of 780,159,243,686,624 with Prime Factorization

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

2 x 2 x 3 x 13 x 5 x 53 x 81 x 343 x 4 = 4594196880

Therefore, the lowest common multiple of 780,159,243,686,624 is 4594196880.

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 159 x 243 x 686 x 624 = 12900504839040

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

159 : 1, 3, 53, 159

243 : 1, 3, 9, 27, 81, 243

686 : 1, 2, 7, 14, 49, 98, 343, 686

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,159,243,686,624, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

159:3x 53

243:3x 3x 3x 3x 3

686:2x 7x 7x 7

624:2x 2x 2x 2x 3x 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 2x 3x 3x 3x 13 = 2808

Therefore, the value for common factors is 2808.

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 = 12900504839040/(1x2808)

LCM = 12900504839040/2808

LCM = 4594196880

Thus, we can understand that the LCM of 780,159,243,686,624 is 4594196880.
