Calculate the LCM of 421,345,657,269

Given numbers are 421,345,657,269

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

The LCM of 421,345,657,269 is 8556528195.

Find LCM of 421,345,657,269 with Prime Factorization


3 421, 345, 657, 269
421, 115, 219, 269

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

3 x 421 x 115 x 219 x 269 = 8556528195

Therefore, the lowest common multiple of 421,345,657,269 is 8556528195.

LCM Formula to Find Lowest Common Multiple of 421,345,657,269

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.

421 x 345 x 657 x 269 = 25669584585

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.

421 : 1, 421

345 : 1, 3, 5, 15, 23, 69, 115, 345

657 : 1, 3, 9, 73, 219, 657

269 : 1, 269

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,345,657,269, is 1.

Now, the common factors can be found like this.

421:421

345:3x 5x 23

657:3x 3x 73

269:269

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

3 = 3

Therefore, the value for common factors is 3.

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 = 25669584585/(1x3)

LCM = 25669584585/3

LCM = 8556528195

Thus, we can understand that the LCM of 421,345,657,269 is 8556528195.
