Given numbers are 662,981,109,940

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

The LCM of 662,981,109,940 is 305228340.

Find LCM of 662,981,109,940 with Prime Factorization

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

2 x 109 x 331 x 9 x 1 x 470 = 305228340

Therefore, the lowest common multiple of 662,981,109,940 is 305228340.

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.

662 x 981 x 109 x 940 = 66539778120

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.

662 : 1, 2, 331, 662

981 : 1, 3, 9, 109, 327, 981

109 : 1, 109

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,981,109,940, is 1.

Now, the common factors can be found like this.

662:2x 331

981:3x 3x 109

109:109

940:2x 2x 5x 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 109 = 218

Therefore, the value for common factors is 218.

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 = 66539778120/(1x218)

LCM = 66539778120/218

LCM = 305228340

Thus, we can understand that the LCM of 662,981,109,940 is 305228340.
