Given numbers are 981,993,654,655

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

The LCM of 981,993,654,655 is 425371410.

Find LCM of 981,993,654,655 with Prime Factorization

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

3 x 109 x 3 x 331 x 2 x 655 = 425371410

Therefore, the lowest common multiple of 981,993,654,655 is 425371410.

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.

981 x 993 x 654 x 655 = 417289353210

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.

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

993 : 1, 3, 331, 993

654 : 1, 2, 3, 6, 109, 218, 327, 654

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,993,654,655, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

993:3x 331

654:2x 3x 109

655:5x 131

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

3x 3x 109 = 981

Therefore, the value for common factors is 981.

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 = 417289353210/(1x981)

LCM = 417289353210/981

LCM = 425371410

Thus, we can understand that the LCM of 981,993,654,655 is 425371410.
