Given numbers are 419,219,646,133

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

The LCM of 419,219,646,133 is 414943242.

Find LCM of 419,219,646,133 with Prime Factorization

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

19 x 419 x 219 x 34 x 7 = 414943242

Therefore, the lowest common multiple of 419,219,646,133 is 414943242.

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.

419 x 219 x 646 x 133 = 7883921598

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.

419 : 1, 419

219 : 1, 3, 73, 219

646 : 1, 2, 17, 19, 34, 38, 323, 646

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,219,646,133, is 1.

Now, the common factors can be found like this.

419:419

219:3x 73

646:2x 17x 19

133:7x 19

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 = 7883921598/(1x19)

LCM = 7883921598/19

LCM = 414943242

Thus, we can understand that the LCM of 419,219,646,133 is 414943242.
