Given numbers are 661,505,243,661

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

The LCM of 661,505,243,661 is 81114615.

Find LCM of 661,505,243,661 with Prime Factorization

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

661 x 1 x 505 x 243 x 1 = 81114615

Therefore, the lowest common multiple of 661,505,243,661 is 81114615.

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.

661 x 505 x 243 x 661 = 53616760515

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.

661 : 1, 661

505 : 1, 5, 101, 505

243 : 1, 3, 9, 27, 81, 243

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,505,243,661, is 1.

Now, the common factors can be found like this.

661:661

505:5x 101

243:3x 3x 3x 3x 3

661:661

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

661 = 661

Therefore, the value for common factors is 661.

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 = 53616760515/(1x661)

LCM = 53616760515/661

LCM = 81114615

Thus, we can understand that the LCM of 661,505,243,661 is 81114615.
