Given numbers are 247,436,742,681

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

The LCM of 247,436,742,681 is 27208491492.

Find LCM of 247,436,742,681 with Prime Factorization

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

2 x 247 x 218 x 371 x 681 = 27208491492

Therefore, the lowest common multiple of 247,436,742,681 is 27208491492.

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 436 x 742 x 681 = 54416982984

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

436 : 1, 2, 4, 109, 218, 436

742 : 1, 2, 7, 14, 53, 106, 371, 742

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,436,742,681, is 1.

Now, the common factors can be found like this.

247:13x 19

436:2x 2x 109

742:2x 7x 53

681:3x 227

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

2 = 2

Therefore, the value for common factors is 2.

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 = 54416982984/(1x2)

LCM = 54416982984/2

LCM = 27208491492

Thus, we can understand that the LCM of 247,436,742,681 is 27208491492.
