Given numbers are 442,831,388,711,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,831,388,711,225 is 422195283900.
Find LCM of 442,831,388,711,225 with Prime Factorization
2 | 442, 831, 388, 711, 225 |
3 | 221, 831, 194, 711, 225 |
3 | 221, 277, 194, 237, 75 |
221, 277, 194, 79, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 221 x 277 x 194 x 79 x 25 = 422195283900
Therefore, the lowest common multiple of 442,831,388,711,225 is 422195283900.
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.
442 x 831 x 388 x 711 x 225 = 22798545330600
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
831 : 1, 3, 277, 831
388 : 1, 2, 4, 97, 194, 388
711 : 1, 3, 9, 79, 237, 711
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,831,388,711,225, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
831:3x 277
388:2x 2x 97
711:3x 3x 79
225:3x 3x 5x 5
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 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 22798545330600/(1x54)
LCM = 22798545330600/54
LCM = 422195283900
Thus, we can understand that the LCM of 442,831,388,711,225 is 422195283900.
