Calculate the LCM of 275,391,161,209

Given numbers are 275,391,161,209

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

The LCM of 275,391,161,209 is 14300825.

Find LCM of 275,391,161,209 with Prime Factorization


11 275, 391, 161, 209
23 25, 391, 161, 19
25, 17, 7, 19

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

11 x 23 x 25 x 17 x 7 x 19 = 14300825

Therefore, the lowest common multiple of 275,391,161,209 is 14300825.

LCM Formula to Find Lowest Common Multiple of 275,391,161,209

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.

275 x 391 x 161 x 209 = 3618108725

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.

275 : 1, 5, 11, 25, 55, 275

391 : 1, 17, 23, 391

161 : 1, 7, 23, 161

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,391,161,209, is 1.

Now, the common factors can be found like this.

275:5x 5x 11

391:17x 23

161:7x 23

209:11x 19

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

11x 23 = 253

Therefore, the value for common factors is 253.

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 = 3618108725/(1x253)

LCM = 3618108725/253

LCM = 14300825

Thus, we can understand that the LCM of 275,391,161,209 is 14300825.
