Given numbers are 247,871,486,641

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

The LCM of 247,871,486,641 is 5155443774.

Find LCM of 247,871,486,641 with Prime Factorization

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

13 x 19 x 67 x 486 x 641 = 5155443774

Therefore, the lowest common multiple of 247,871,486,641 is 5155443774.

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.

247 x 871 x 486 x 641 = 67020769062

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.

247 : 1, 13, 19, 247

871 : 1, 13, 67, 871

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,871,486,641, is 1.

Now, the common factors can be found like this.

247:13x 19

871:13x 67

486:2x 3x 3x 3x 3x 3

641:641

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

13 = 13

Therefore, the value for common factors is 13.

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 = 67020769062/(1x13)

LCM = 67020769062/13

LCM = 5155443774

Thus, we can understand that the LCM of 247,871,486,641 is 5155443774.
