Calculate the LCM of 289,428,838,137

Given numbers are 289,428,838,137

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

The LCM of 289,428,838,137 is 7100291876.

Find LCM of 289,428,838,137 with Prime Factorization


2 289, 428, 838, 137
289, 214, 419, 137

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

2 x 289 x 214 x 419 x 137 = 7100291876

Therefore, the lowest common multiple of 289,428,838,137 is 7100291876.

LCM Formula to Find Lowest Common Multiple of 289,428,838,137

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 428 x 838 x 137 = 14200583752

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

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

838 : 1, 2, 419, 838

137 : 1, 137

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,428,838,137, is 1.

Now, the common factors can be found like this.

289:17x 17

428:2x 2x 107

838:2x 419

137:137

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

2 = 2

Therefore, the value for common factors is 2.

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 = 14200583752/(1x2)

LCM = 14200583752/2

LCM = 7100291876

Thus, we can understand that the LCM of 289,428,838,137 is 7100291876.
