Given numbers are 781,871,866,117

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

The LCM of 781,871,866,117 is 5301876294.

Find LCM of 781,871,866,117 with Prime Factorization

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

13 x 781 x 67 x 866 x 9 = 5301876294

Therefore, the lowest common multiple of 781,871,866,117 is 5301876294.

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.

781 x 871 x 866 x 117 = 68924391822

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.

781 : 1, 11, 71, 781

871 : 1, 13, 67, 871

866 : 1, 2, 433, 866

117 : 1, 3, 9, 13, 39, 117

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,871,866,117, is 1.

Now, the common factors can be found like this.

781:11x 71

871:13x 67

866:2x 433

117:3x 3x 13

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 = 68924391822/(1x13)

LCM = 68924391822/13

LCM = 5301876294

Thus, we can understand that the LCM of 781,871,866,117 is 5301876294.
