Given numbers are 523,661,221,585

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

The LCM of 523,661,221,585 is 3438016335.

Find LCM of 523,661,221,585 with Prime Factorization

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

13 x 523 x 661 x 17 x 45 = 3438016335

Therefore, the lowest common multiple of 523,661,221,585 is 3438016335.

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.

523 x 661 x 221 x 585 = 44694212355

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.

523 : 1, 523

661 : 1, 661

221 : 1, 13, 17, 221

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,661,221,585, is 1.

Now, the common factors can be found like this.

523:523

661:661

221:13x 17

585:3x 3x 5x 13

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 = 44694212355/(1x13)

LCM = 44694212355/13

LCM = 3438016335

Thus, we can understand that the LCM of 523,661,221,585 is 3438016335.
