Given numbers are 269,205,815,420

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

The LCM of 269,205,815,420 is 755045340.

Find LCM of 269,205,815,420 with Prime Factorization

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

5 x 269 x 41 x 163 x 84 = 755045340

Therefore, the lowest common multiple of 269,205,815,420 is 755045340.

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.

269 x 205 x 815 x 420 = 18876133500

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.

269 : 1, 269

205 : 1, 5, 41, 205

815 : 1, 5, 163, 815

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 269,205,815,420, is 1.

Now, the common factors can be found like this.

269:269

205:5x 41

815:5x 163

420:2x 2x 3x 5x 7

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 18876133500/(1x25)

LCM = 18876133500/25

LCM = 755045340

Thus, we can understand that the LCM of 269,205,815,420 is 755045340.
