Given numbers are 218,263,842,661

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

The LCM of 218,263,842,661 is 15954962854.

Find LCM of 218,263,842,661 with Prime Factorization

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

2 x 109 x 263 x 421 x 661 = 15954962854

Therefore, the lowest common multiple of 218,263,842,661 is 15954962854.

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.

218 x 263 x 842 x 661 = 31909925708

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.

218 : 1, 2, 109, 218

263 : 1, 263

842 : 1, 2, 421, 842

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,263,842,661, is 1.

Now, the common factors can be found like this.

218:2x 109

263:263

842:2x 421

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.

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 = 31909925708/(1x2)

LCM = 31909925708/2

LCM = 15954962854

Thus, we can understand that the LCM of 218,263,842,661 is 15954962854.
