Calculate the LCM of 521,988,381,542

Given numbers are 521,988,381,542

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

The LCM of 521,988,381,542 is 53148245748.

Find LCM of 521,988,381,542 with Prime Factorization


2 521, 988, 381, 542
521, 494, 381, 271

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

2 x 521 x 494 x 381 x 271 = 53148245748

Therefore, the lowest common multiple of 521,988,381,542 is 53148245748.

LCM Formula to Find Lowest Common Multiple of 521,988,381,542

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.

521 x 988 x 381 x 542 = 106296491496

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.

521 : 1, 521

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

381 : 1, 3, 127, 381

542 : 1, 2, 271, 542

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,988,381,542, is 1.

Now, the common factors can be found like this.

521:521

988:2x 2x 13x 19

381:3x 127

542:2x 271

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 = 106296491496/(1x2)

LCM = 106296491496/2

LCM = 53148245748

Thus, we can understand that the LCM of 521,988,381,542 is 53148245748.
