Calculate the LCM of 521,247,728,561

Given numbers are 521,247,728,561

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

The LCM of 521,247,728,561 is 4042830792.

Find LCM of 521,247,728,561 with Prime Factorization


13 521, 247, 728, 561
521, 19, 56, 561

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

13 x 521 x 19 x 56 x 561 = 4042830792

Therefore, the lowest common multiple of 521,247,728,561 is 4042830792.

LCM Formula to Find Lowest Common Multiple of 521,247,728,561

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 247 x 728 x 561 = 52556800296

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

247 : 1, 13, 19, 247

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

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,247,728,561, is 1.

Now, the common factors can be found like this.

521:521

247:13x 19

728:2x 2x 2x 7x 13

561:3x 11x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 52556800296/(1x13)

LCM = 52556800296/13

LCM = 4042830792

Thus, we can understand that the LCM of 521,247,728,561 is 4042830792.
