Given numbers are 780,438,244,863,536

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

The LCM of 780,438,244,863,536 is 401663984280.

Find LCM of 780,438,244,863,536 with Prime Factorization

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

2 x 2 x 3 x 65 x 73 x 61 x 863 x 134 = 401663984280

Therefore, the lowest common multiple of 780,438,244,863,536 is 401663984280.

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 438 x 244 x 863 x 536 = 38559742490880

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

438 : 1, 2, 3, 6, 73, 146, 219, 438

244 : 1, 2, 4, 61, 122, 244

863 : 1, 863

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,438,244,863,536, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

438:2x 3x 73

244:2x 2x 61

863:863

536:2x 2x 2x 67

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 3 = 96

Therefore, the value for common factors is 96.

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 = 38559742490880/(1x96)

LCM = 38559742490880/96

LCM = 401663984280

Thus, we can understand that the LCM of 780,438,244,863,536 is 401663984280.
