Given numbers are 169,643,643,305

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

The LCM of 169,643,643,305 is 33143435.

Find LCM of 169,643,643,305 with Prime Factorization

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

643 x 169 x 1 x 1 x 305 = 33143435

Therefore, the lowest common multiple of 169,643,643,305 is 33143435.

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.

169 x 643 x 643 x 305 = 21311228705

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.

169 : 1, 13, 169

643 : 1, 643

643 : 1, 643

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,643,643,305, is 1.

Now, the common factors can be found like this.

169:13x 13

643:643

643:643

305:5x 61

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

643 = 643

Therefore, the value for common factors is 643.

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 = 21311228705/(1x643)

LCM = 21311228705/643

LCM = 33143435

Thus, we can understand that the LCM of 169,643,643,305 is 33143435.
