Calculate the LCM of 418,442,247

Given numbers are 418,442,247

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

The LCM of 418,442,247 is 92378.

Find LCM of 418,442,247 with Prime Factorization


2 418, 442, 247
13 209, 221, 247
19 209, 17, 19
11, 17, 1

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

2 x 13 x 19 x 11 x 17 x 1 = 92378

Therefore, the lowest common multiple of 418,442,247 is 92378.

LCM Formula to Find Lowest Common Multiple of 418,442,247

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.

418 x 442 x 247 = 45634732

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

442 : 1, 2, 13, 17, 26, 34, 221, 442

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,442,247, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

442:2x 13x 17

247:13x 19

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

2x 13x 19 = 494

Therefore, the value for common factors is 494.

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 = 45634732/(1x494)

LCM = 45634732/494

LCM = 92378

Thus, we can understand that the LCM of 418,442,247 is 92378.
