Calculate the LCM of 868,299,689,689

Given numbers are 868,299,689,689

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

The LCM of 868,299,689,689 is 13755196.

Find LCM of 868,299,689,689 with Prime Factorization


13 868, 299, 689, 689
53 868, 23, 53, 53
868, 23, 1, 1

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

13 x 53 x 868 x 23 x 1 x 1 = 13755196

Therefore, the lowest common multiple of 868,299,689,689 is 13755196.

LCM Formula to Find Lowest Common Multiple of 868,299,689,689

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.

868 x 299 x 689 x 689 = 123205290572

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

299 : 1, 13, 23, 299

689 : 1, 13, 53, 689

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,299,689,689, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

299:13x 23

689:13x 53

689:13x 53

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

13x 13x 53 = 8957

Therefore, the value for common factors is 8957.

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 = 123205290572/(1x8957)

LCM = 123205290572/8957

LCM = 13755196

Thus, we can understand that the LCM of 868,299,689,689 is 13755196.
