Calculate the LCM of 409,306,288,431

Given numbers are 409,306,288,431

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

The LCM of 409,306,288,431 is 863061984.

Find LCM of 409,306,288,431 with Prime Factorization


2 409, 306, 288, 431
3 409, 153, 144, 431
3 409, 51, 48, 431
409, 17, 16, 431

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

2 x 3 x 3 x 409 x 17 x 16 x 431 = 863061984

Therefore, the lowest common multiple of 409,306,288,431 is 863061984.

LCM Formula to Find Lowest Common Multiple of 409,306,288,431

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.

409 x 306 x 288 x 431 = 15535115712

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.

409 : 1, 409

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,306,288,431, is 1.

Now, the common factors can be found like this.

409:409

306:2x 3x 3x 17

288:2x 2x 2x 2x 2x 3x 3

431:431

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 15535115712/(1x18)

LCM = 15535115712/18

LCM = 863061984

Thus, we can understand that the LCM of 409,306,288,431 is 863061984.
