Calculate the LCM of 477,321,285,684

Given numbers are 477,321,285,684

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

The LCM of 477,321,285,684 is 19394820.

Find LCM of 477,321,285,684 with Prime Factorization


3 477, 321, 285, 684
3 159, 107, 95, 228
19 53, 107, 95, 76
53, 107, 5, 4

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

3 x 3 x 19 x 53 x 107 x 5 x 4 = 19394820

Therefore, the lowest common multiple of 477,321,285,684 is 19394820.

LCM Formula to Find Lowest Common Multiple of 477,321,285,684

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.

477 x 321 x 285 x 684 = 29848627980

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.

477 : 1, 3, 9, 53, 159, 477

321 : 1, 3, 107, 321

285 : 1, 3, 5, 15, 19, 57, 95, 285

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,321,285,684, is 3.

Now, the common factors can be found like this.

477:3x 3x 53

321:3x 107

285:3x 5x 19

684:2x 2x 3x 3x 19

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

3x 3x 3x 19 = 513

Therefore, the value for common factors is 513.

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 = 29848627980/(3x513)

LCM = 29848627980/1539

LCM = 19394820

Thus, we can understand that the LCM of 477,321,285,684 is 19394820.
