Given numbers are 604,198,209,689

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

The LCM of 604,198,209,689 is 782789436.

Find LCM of 604,198,209,689 with Prime Factorization

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

2 x 11 x 302 x 9 x 19 x 689 = 782789436

Therefore, the lowest common multiple of 604,198,209,689 is 782789436.

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.

604 x 198 x 209 x 689 = 17221367592

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.

604 : 1, 2, 4, 151, 302, 604

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

209 : 1, 11, 19, 209

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 604,198,209,689, is 1.

Now, the common factors can be found like this.

604:2x 2x 151

198:2x 3x 3x 11

209:11x 19

689:13x 53

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 17221367592/(1x22)

LCM = 17221367592/22

LCM = 782789436

Thus, we can understand that the LCM of 604,198,209,689 is 782789436.
