Given numbers are 811,190,689,871

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

The LCM of 811,190,689,871 is 7113256670.

Find LCM of 811,190,689,871 with Prime Factorization

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

13 x 811 x 190 x 53 x 67 = 7113256670

Therefore, the lowest common multiple of 811,190,689,871 is 7113256670.

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.

811 x 190 x 689 x 871 = 92472336710

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.

811 : 1, 811

190 : 1, 2, 5, 10, 19, 38, 95, 190

689 : 1, 13, 53, 689

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,190,689,871, is 1.

Now, the common factors can be found like this.

811:811

190:2x 5x 19

689:13x 53

871:13x 67

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 = 92472336710/(1x13)

LCM = 92472336710/13

LCM = 7113256670

Thus, we can understand that the LCM of 811,190,689,871 is 7113256670.
