Calculate the LCM of 289,856,681,616

Given numbers are 289,856,681,616

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

The LCM of 289,856,681,616 is 12972074808.

Find LCM of 289,856,681,616 with Prime Factorization


2 289, 856, 681, 616
2 289, 428, 681, 308
2 289, 214, 681, 154
289, 107, 681, 77

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

2 x 2 x 2 x 289 x 107 x 681 x 77 = 12972074808

Therefore, the lowest common multiple of 289,856,681,616 is 12972074808.

LCM Formula to Find Lowest Common Multiple of 289,856,681,616

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.

289 x 856 x 681 x 616 = 103776598464

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.

289 : 1, 17, 289

856 : 1, 2, 4, 8, 107, 214, 428, 856

681 : 1, 3, 227, 681

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,856,681,616, is 1.

Now, the common factors can be found like this.

289:17x 17

856:2x 2x 2x 107

681:3x 227

616:2x 2x 2x 7x 11

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 103776598464/(1x8)

LCM = 103776598464/8

LCM = 12972074808

Thus, we can understand that the LCM of 289,856,681,616 is 12972074808.
