Calculate the LCM of 138,497,323,988

Given numbers are 138,497,323,988

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

The LCM of 138,497,323,988 is 575985228.

Find LCM of 138,497,323,988 with Prime Factorization


2 138, 497, 323, 988
19 69, 497, 323, 494
69, 497, 17, 26

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

2 x 19 x 69 x 497 x 17 x 26 = 575985228

Therefore, the lowest common multiple of 138,497,323,988 is 575985228.

LCM Formula to Find Lowest Common Multiple of 138,497,323,988

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.

138 x 497 x 323 x 988 = 21887438664

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

497 : 1, 7, 71, 497

323 : 1, 17, 19, 323

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,497,323,988, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

497:7x 71

323:17x 19

988:2x 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 19 = 38

Therefore, the value for common factors is 38.

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 = 21887438664/(1x38)

LCM = 21887438664/38

LCM = 575985228

Thus, we can understand that the LCM of 138,497,323,988 is 575985228.
