Given numbers are 997,261,489,860

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

The LCM of 997,261,489,860 is 36477219060.

Find LCM of 997,261,489,860 with Prime Factorization

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

3 x 997 x 87 x 163 x 860 = 36477219060

Therefore, the lowest common multiple of 997,261,489,860 is 36477219060.

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.

997 x 261 x 489 x 860 = 109431657180

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.

997 : 1, 997

261 : 1, 3, 9, 29, 87, 261

489 : 1, 3, 163, 489

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,261,489,860, is 1.

Now, the common factors can be found like this.

997:997

261:3x 3x 29

489:3x 163

860:2x 2x 5x 43

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

3 = 3

Therefore, the value for common factors is 3.

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 = 109431657180/(1x3)

LCM = 109431657180/3

LCM = 36477219060

Thus, we can understand that the LCM of 997,261,489,860 is 36477219060.
