Given numbers are 780,808,644,536,744

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

The LCM of 780,808,644,536,744 is 52687591320.

Find LCM of 780,808,644,536,744 with Prime Factorization

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

2 x 2 x 2 x 3 x 65 x 101 x 161 x 67 x 31 = 52687591320

Therefore, the lowest common multiple of 780,808,644,536,744 is 52687591320.

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 808 x 644 x 536 x 744 = 161856280535040

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

808 : 1, 2, 4, 8, 101, 202, 404, 808

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

536 : 1, 2, 4, 8, 67, 134, 268, 536

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,808,644,536,744, is 4.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

808:2x 2x 2x 101

644:2x 2x 7x 23

536:2x 2x 2x 67

744:2x 2x 2x 3x 31

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 2x 2x 2x 2x 2x 3 = 768

Therefore, the value for common factors is 768.

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 = 161856280535040/(4x768)

LCM = 161856280535040/3072

LCM = 52687591320

Thus, we can understand that the LCM of 780,808,644,536,744 is 52687591320.
