Given numbers are 198,154,781,209,611

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

The LCM of 198,154,781,209,611 is 1142395254.

Find LCM of 198,154,781,209,611 with Prime Factorization

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

2 x 11 x 9 x 7 x 71 x 19 x 611 = 1142395254

Therefore, the lowest common multiple of 198,154,781,209,611 is 1142395254.

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.

198 x 154 x 781 x 209 x 611 = 3041056166148

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.

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

154 : 1, 2, 7, 11, 14, 22, 77, 154

781 : 1, 11, 71, 781

209 : 1, 11, 19, 209

611 : 1, 13, 47, 611

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,154,781,209,611, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

154:2x 7x 11

781:11x 71

209:11x 19

611:13x 47

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 11x 11 = 2662

Therefore, the value for common factors is 2662.

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 = 3041056166148/(1x2662)

LCM = 3041056166148/2662

LCM = 1142395254

Thus, we can understand that the LCM of 198,154,781,209,611 is 1142395254.
