Given numbers are 661,538,982,212

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

The LCM of 661,538,982,212 is 18508494428.

Find LCM of 661,538,982,212 with Prime Factorization

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

2 x 661 x 269 x 491 x 106 = 18508494428

Therefore, the lowest common multiple of 661,538,982,212 is 18508494428.

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 538 x 982 x 212 = 74033977712

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

538 : 1, 2, 269, 538

982 : 1, 2, 491, 982

212 : 1, 2, 4, 53, 106, 212

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,538,982,212, is 1.

Now, the common factors can be found like this.

661:661

538:2x 269

982:2x 491

212:2x 2x 53

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 74033977712/(1x4)

LCM = 74033977712/4

LCM = 18508494428

Thus, we can understand that the LCM of 661,538,982,212 is 18508494428.
