Calculate the LCM of 622,648,285,552

Given numbers are 622,648,285,552

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

The LCM of 622,648,285,552 is 440338680.

Find LCM of 622,648,285,552 with Prime Factorization


2 622, 648, 285, 552
2 311, 324, 285, 276
2 311, 162, 285, 138
3 311, 81, 285, 69
311, 27, 95, 23

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

2 x 2 x 2 x 3 x 311 x 27 x 95 x 23 = 440338680

Therefore, the lowest common multiple of 622,648,285,552 is 440338680.

LCM Formula to Find Lowest Common Multiple of 622,648,285,552

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.

622 x 648 x 285 x 552 = 63408769920

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.

622 : 1, 2, 311, 622

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

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

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,648,285,552, is 1.

Now, the common factors can be found like this.

622:2x 311

648:2x 2x 2x 3x 3x 3x 3

285:3x 5x 19

552:2x 2x 2x 3x 23

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

2x 2x 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 63408769920/(1x144)

LCM = 63408769920/144

LCM = 440338680

Thus, we can understand that the LCM of 622,648,285,552 is 440338680.
