Given numbers are 782,472,194,780,520

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

The LCM of 782,472,194,780,520 is 3490801080.

Find LCM of 782,472,194,780,520 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 391 x 59 x 97 x 3 x 1 = 3490801080

Therefore, the lowest common multiple of 782,472,194,780,520 is 3490801080.

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.

782 x 472 x 194 x 780 x 520 = 29043464985600

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

472 : 1, 2, 4, 8, 59, 118, 236, 472

194 : 1, 2, 97, 194

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

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,472,194,780,520, is 2.

Now, the common factors can be found like this.

782:2x 17x 23

472:2x 2x 2x 59

194:2x 97

780:2x 2x 3x 5x 13

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 2x 2x 2x 2x 5x 13 = 4160

Therefore, the value for common factors is 4160.

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 = 29043464985600/(2x4160)

LCM = 29043464985600/8320

LCM = 3490801080

Thus, we can understand that the LCM of 782,472,194,780,520 is 3490801080.
