Calculate the LCM of 221,897,161,425

Given numbers are 221,897,161,425

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

The LCM of 221,897,161,425 is 2668575.

Find LCM of 221,897,161,425 with Prime Factorization


13 221, 897, 161, 425
17 17, 69, 161, 425
23 1, 69, 161, 25
1, 3, 7, 25

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

13 x 17 x 23 x 1 x 3 x 7 x 25 = 2668575

Therefore, the lowest common multiple of 221,897,161,425 is 2668575.

LCM Formula to Find Lowest Common Multiple of 221,897,161,425

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.

221 x 897 x 161 x 425 = 13564366725

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.

221 : 1, 13, 17, 221

897 : 1, 3, 13, 23, 39, 69, 299, 897

161 : 1, 7, 23, 161

425 : 1, 5, 17, 25, 85, 425

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,897,161,425, is 1.

Now, the common factors can be found like this.

221:13x 17

897:3x 13x 23

161:7x 23

425:5x 5x 17

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

13x 17x 23 = 5083

Therefore, the value for common factors is 5083.

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 = 13564366725/(1x5083)

LCM = 13564366725/5083

LCM = 2668575

Thus, we can understand that the LCM of 221,897,161,425 is 2668575.
