Given numbers are 661,412,618,173

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

The LCM of 661,412,618,173 is 141340308.

Find LCM of 661,412,618,173 with Prime Factorization

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

2 x 103 x 661 x 2 x 3 x 173 = 141340308

Therefore, the lowest common multiple of 661,412,618,173 is 141340308.

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 412 x 618 x 173 = 29116103448

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

412 : 1, 2, 4, 103, 206, 412

618 : 1, 2, 3, 6, 103, 206, 309, 618

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,412,618,173, is 1.

Now, the common factors can be found like this.

661:661

412:2x 2x 103

618:2x 3x 103

173:173

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 29116103448/(1x206)

LCM = 29116103448/206

LCM = 141340308

Thus, we can understand that the LCM of 661,412,618,173 is 141340308.
