Given numbers are 681,397,623,397

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

The LCM of 681,397,623,397 is 168432411.

Find LCM of 681,397,623,397 with Prime Factorization

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

397 x 681 x 1 x 623 x 1 = 168432411

Therefore, the lowest common multiple of 681,397,623,397 is 168432411.

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.

681 x 397 x 623 x 397 = 66867667167

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.

681 : 1, 3, 227, 681

397 : 1, 397

623 : 1, 7, 89, 623

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,397,623,397, is 1.

Now, the common factors can be found like this.

681:3x 227

397:397

623:7x 89

397:397

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

397 = 397

Therefore, the value for common factors is 397.

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 = 66867667167/(1x397)

LCM = 66867667167/397

LCM = 168432411

Thus, we can understand that the LCM of 681,397,623,397 is 168432411.
