Given numbers are 247,419,722,421

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

The LCM of 247,419,722,421 is 1655681014.

Find LCM of 247,419,722,421 with Prime Factorization

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

19 x 13 x 419 x 38 x 421 = 1655681014

Therefore, the lowest common multiple of 247,419,722,421 is 1655681014.

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 419 x 722 x 421 = 31457939266

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

419 : 1, 419

722 : 1, 2, 19, 38, 361, 722

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,419,722,421, is 1.

Now, the common factors can be found like this.

247:13x 19

419:419

722:2x 19x 19

421:421

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

19 = 19

Therefore, the value for common factors is 19.

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 = 31457939266/(1x19)

LCM = 31457939266/19

LCM = 1655681014

Thus, we can understand that the LCM of 247,419,722,421 is 1655681014.
