Given numbers are 661,281,597,398

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

The LCM of 661,281,597,398 is 221774754.

Find LCM of 661,281,597,398 with Prime Factorization

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

199 x 661 x 281 x 3 x 2 = 221774754

Therefore, the lowest common multiple of 661,281,597,398 is 221774754.

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 281 x 597 x 398 = 44133176046

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

281 : 1, 281

597 : 1, 3, 199, 597

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,281,597,398, is 1.

Now, the common factors can be found like this.

661:661

281:281

597:3x 199

398:2x 199

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

199 = 199

Therefore, the value for common factors is 199.

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 = 44133176046/(1x199)

LCM = 44133176046/199

LCM = 221774754

Thus, we can understand that the LCM of 661,281,597,398 is 221774754.
