Given numbers are 247,871,865,847

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

The LCM of 247,871,865,847 is 12124707595.

Find LCM of 247,871,865,847 with Prime Factorization

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

13 x 19 x 67 x 865 x 847 = 12124707595

Therefore, the lowest common multiple of 247,871,865,847 is 12124707595.

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 865 x 847 = 157621198735

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

865 : 1, 5, 173, 865

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,871,865,847, is 1.

Now, the common factors can be found like this.

247:13x 19

871:13x 67

865:5x 173

847:7x 11x 11

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 = 157621198735/(1x13)

LCM = 157621198735/13

LCM = 12124707595

Thus, we can understand that the LCM of 247,871,865,847 is 12124707595.
