Given numbers are 247,711,728,214,394

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

The LCM of 247,711,728,214,394 is 207302521608.

Find LCM of 247,711,728,214,394 with Prime Factorization

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

2 x 13 x 19 x 711 x 28 x 107 x 197 = 207302521608

Therefore, the lowest common multiple of 247,711,728,214,394 is 207302521608.

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.

247 x 711 x 728 x 214 x 394 = 10779731123616

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.

247 : 1, 13, 19, 247

711 : 1, 3, 9, 79, 237, 711

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

214 : 1, 2, 107, 214

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,711,728,214,394, is 1.

Now, the common factors can be found like this.

247:13x 19

711:3x 3x 79

728:2x 2x 2x 7x 13

214:2x 107

394:2x 197

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 13 = 52

Therefore, the value for common factors is 52.

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 = 10779731123616/(1x52)

LCM = 10779731123616/52

LCM = 207302521608

Thus, we can understand that the LCM of 247,711,728,214,394 is 207302521608.
