Calculate the LCM of 242,121,249,478

Given numbers are 242,121,249,478

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

The LCM of 242,121,249,478 is 14401662.

Find LCM of 242,121,249,478 with Prime Factorization


2 242, 121, 249, 478
11 121, 121, 249, 239
11 11, 11, 249, 239
1, 1, 249, 239

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

2 x 11 x 11 x 1 x 1 x 249 x 239 = 14401662

Therefore, the lowest common multiple of 242,121,249,478 is 14401662.

LCM Formula to Find Lowest Common Multiple of 242,121,249,478

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.

242 x 121 x 249 x 478 = 3485202204

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.

242 : 1, 2, 11, 22, 121, 242

121 : 1, 11, 121

249 : 1, 3, 83, 249

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,121,249,478, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

121:11x 11

249:3x 83

478:2x 239

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 3485202204/(1x242)

LCM = 3485202204/242

LCM = 14401662

Thus, we can understand that the LCM of 242,121,249,478 is 14401662.
