Calculate the LCM of 351,197,221,663

Given numbers are 351,197,221,663

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

The LCM of 351,197,221,663 is 1175499.

Find LCM of 351,197,221,663 with Prime Factorization


3 351, 197, 221, 663
13 117, 197, 221, 221
17 9, 197, 17, 17
9, 197, 1, 1

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

3 x 13 x 17 x 9 x 197 x 1 x 1 = 1175499

Therefore, the lowest common multiple of 351,197,221,663 is 1175499.

LCM Formula to Find Lowest Common Multiple of 351,197,221,663

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.

351 x 197 x 221 x 663 = 10131625881

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

197 : 1, 197

221 : 1, 13, 17, 221

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,197,221,663, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

197:197

221:13x 17

663:3x 13x 17

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

3x 13x 13x 17 = 8619

Therefore, the value for common factors is 8619.

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 = 10131625881/(1x8619)

LCM = 10131625881/8619

LCM = 1175499

Thus, we can understand that the LCM of 351,197,221,663 is 1175499.
