The LCM of 281,209,748,494 is 51916436.

Find LCM of 281,209,748,494 with Prime Factorization


2 281, 209, 748, 494
11 281, 209, 374, 247
19 281, 19, 34, 247
281, 1, 34, 13

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

2 x 11 x 19 x 281 x 1 x 34 x 13 = 51916436

Therefore, the lowest common multiple of 281,209,748,494 is 51916436.

LCM Formula to Find Lowest Common Multiple of 281,209,748,494

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 209 x 748 x 494 = 21701070248

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

209 : 1, 11, 19, 209

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

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,209,748,494, is 1.

Now, the common factors can be found like this.

281:281

209:11x 19

748:2x 2x 11x 17

494:2x 13x 19

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

2x 11x 19 = 418

Therefore, the value for common factors is 418.

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 = 21701070248/(1x418)

LCM = 21701070248/418

LCM = 51916436

Thus, we can understand that the LCM of 281,209,748,494 is 51916436.
