Calculate the LCM of 521,339,974,728

Given numbers are 521,339,974,728

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

The LCM of 521,339,974,728 is 62617793784.

Find LCM of 521,339,974,728 with Prime Factorization


2 521, 339, 974, 728
521, 339, 487, 364

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

2 x 521 x 339 x 487 x 364 = 62617793784

Therefore, the lowest common multiple of 521,339,974,728 is 62617793784.

LCM Formula to Find Lowest Common Multiple of 521,339,974,728

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 339 x 974 x 728 = 125235587568

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

339 : 1, 3, 113, 339

974 : 1, 2, 487, 974

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,339,974,728, is 1.

Now, the common factors can be found like this.

521:521

339:3x 113

974:2x 487

728:2x 2x 2x 7x 13

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 = 125235587568/(1x2)

LCM = 125235587568/2

LCM = 62617793784

Thus, we can understand that the LCM of 521,339,974,728 is 62617793784.
