Given numbers are 247,703,429,689

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

The LCM of 247,703,429,689 is 15984111.

Find LCM of 247,703,429,689 with Prime Factorization

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

13 x 19 x 1 x 37 x 33 x 53 = 15984111

Therefore, the lowest common multiple of 247,703,429,689 is 15984111.

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 703 x 429 x 689 = 51324980421

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

703 : 1, 19, 37, 703

429 : 1, 3, 11, 13, 33, 39, 143, 429

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,703,429,689, is 1.

Now, the common factors can be found like this.

247:13x 19

703:19x 37

429:3x 11x 13

689:13x 53

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13x 13x 19 = 3211

Therefore, the value for common factors is 3211.

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 = 51324980421/(1x3211)

LCM = 51324980421/3211

LCM = 15984111

Thus, we can understand that the LCM of 247,703,429,689 is 15984111.
