Given numbers are 247,269,133,421

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

The LCM of 247,269,133,421 is 195807521.

Find LCM of 247,269,133,421 with Prime Factorization

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

19 x 13 x 269 x 7 x 421 = 195807521

Therefore, the lowest common multiple of 247,269,133,421 is 195807521.

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.

247 x 269 x 133 x 421 = 3720342899

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.

247 : 1, 13, 19, 247

269 : 1, 269

133 : 1, 7, 19, 133

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,269,133,421, is 1.

Now, the common factors can be found like this.

247:13x 19

269:269

133:7x 19

421:421

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

19 = 19

Therefore, the value for common factors is 19.

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 = 3720342899/(1x19)

LCM = 3720342899/19

LCM = 195807521

Thus, we can understand that the LCM of 247,269,133,421 is 195807521.
