Given numbers are 202,209,689,618

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

The LCM of 202,209,689,618 is 8988254418.

Find LCM of 202,209,689,618 with Prime Factorization

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

2 x 101 x 209 x 689 x 309 = 8988254418

Therefore, the lowest common multiple of 202,209,689,618 is 8988254418.

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.

202 x 209 x 689 x 618 = 17976508836

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.

202 : 1, 2, 101, 202

209 : 1, 11, 19, 209

689 : 1, 13, 53, 689

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,209,689,618, is 1.

Now, the common factors can be found like this.

202:2x 101

209:11x 19

689:13x 53

618:2x 3x 103

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

2 = 2

Therefore, the value for common factors is 2.

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 = 17976508836/(1x2)

LCM = 17976508836/2

LCM = 8988254418

Thus, we can understand that the LCM of 202,209,689,618 is 8988254418.
