Calculate the LCM of 495,221,209,803

Given numbers are 495,221,209,803

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

The LCM of 495,221,209,803 is 151730865.

Find LCM of 495,221,209,803 with Prime Factorization


11 495, 221, 209, 803
45, 221, 19, 73

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

11 x 45 x 221 x 19 x 73 = 151730865

Therefore, the lowest common multiple of 495,221,209,803 is 151730865.

LCM Formula to Find Lowest Common Multiple of 495,221,209,803

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.

495 x 221 x 209 x 803 = 18359434665

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.

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

221 : 1, 13, 17, 221

209 : 1, 11, 19, 209

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,221,209,803, is 1.

Now, the common factors can be found like this.

495:3x 3x 5x 11

221:13x 17

209:11x 19

803:11x 73

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 18359434665/(1x121)

LCM = 18359434665/121

LCM = 151730865

Thus, we can understand that the LCM of 495,221,209,803 is 151730865.
