Given numbers are 646,473,253,204

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

The LCM of 646,473,253,204 is 42167004.

Find LCM of 646,473,253,204 with Prime Factorization

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

2 x 11 x 17 x 19 x 43 x 23 x 6 = 42167004

Therefore, the lowest common multiple of 646,473,253,204 is 42167004.

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.

646 x 473 x 253 x 204 = 15770459496

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.

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

473 : 1, 11, 43, 473

253 : 1, 11, 23, 253

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,473,253,204, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

473:11x 43

253:11x 23

204:2x 2x 3x 17

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

2x 11x 17 = 374

Therefore, the value for common factors is 374.

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 = 15770459496/(1x374)

LCM = 15770459496/374

LCM = 42167004

Thus, we can understand that the LCM of 646,473,253,204 is 42167004.
