Given numbers are 253,660,209,532

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

The LCM of 253,660,209,532 is 2018940.

Find LCM of 253,660,209,532 with Prime Factorization

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

2 x 2 x 11 x 19 x 23 x 15 x 1 x 7 = 2018940

Therefore, the lowest common multiple of 253,660,209,532 is 2018940.

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.

253 x 660 x 209 x 532 = 18566172240

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.

253 : 1, 11, 23, 253

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

209 : 1, 11, 19, 209

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,660,209,532, is 1.

Now, the common factors can be found like this.

253:11x 23

660:2x 2x 3x 5x 11

209:11x 19

532:2x 2x 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.

2x 2x 11x 11x 19 = 9196

Therefore, the value for common factors is 9196.

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 = 18566172240/(1x9196)

LCM = 18566172240/9196

LCM = 2018940

Thus, we can understand that the LCM of 253,660,209,532 is 2018940.
