Calculate the LCM of 281,748,204,681

Given numbers are 281,748,204,681

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

The LCM of 281,748,204,681 is 143138028.

Find LCM of 281,748,204,681 with Prime Factorization


2 281, 748, 204, 681
2 281, 374, 102, 681
3 281, 187, 51, 681
17 281, 187, 17, 227
281, 11, 1, 227

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

2 x 2 x 3 x 17 x 281 x 11 x 1 x 227 = 143138028

Therefore, the lowest common multiple of 281,748,204,681 is 143138028.

LCM Formula to Find Lowest Common Multiple of 281,748,204,681

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.

281 x 748 x 204 x 681 = 29200157712

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.

281 : 1, 281

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,748,204,681, is 1.

Now, the common factors can be found like this.

281:281

748:2x 2x 11x 17

204:2x 2x 3x 17

681:3x 227

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 3x 17 = 204

Therefore, the value for common factors is 204.

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 = 29200157712/(1x204)

LCM = 29200157712/204

LCM = 143138028

Thus, we can understand that the LCM of 281,748,204,681 is 143138028.
