Given numbers are 198,253,661,687

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

The LCM of 198,253,661,687 is 689334426.

Find LCM of 198,253,661,687 with Prime Factorization

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

3 x 11 x 6 x 23 x 661 x 229 = 689334426

Therefore, the lowest common multiple of 198,253,661,687 is 689334426.

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 253 x 661 x 687 = 22748036058

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

253 : 1, 11, 23, 253

661 : 1, 661

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,253,661,687, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

253:11x 23

661:661

687:3x 229

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

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 22748036058/(1x33)

LCM = 22748036058/33

LCM = 689334426

Thus, we can understand that the LCM of 198,253,661,687 is 689334426.
