Given numbers are 397,180,698,205

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

The LCM of 397,180,698,205 is 1022521140.

Find LCM of 397,180,698,205 with Prime Factorization

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

2 x 5 x 397 x 18 x 349 x 41 = 1022521140

Therefore, the lowest common multiple of 397,180,698,205 is 1022521140.

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.

397 x 180 x 698 x 205 = 10225211400

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.

397 : 1, 397

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

698 : 1, 2, 349, 698

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,180,698,205, is 1.

Now, the common factors can be found like this.

397:397

180:2x 2x 3x 3x 5

698:2x 349

205:5x 41

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 10225211400/(1x10)

LCM = 10225211400/10

LCM = 1022521140

Thus, we can understand that the LCM of 397,180,698,205 is 1022521140.
