Given numbers are 454,660,163,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,660,163,440 is 48841320.
Find LCM of 454,660,163,440 with Prime Factorization
2 | 454, 660, 163, 440 |
2 | 227, 330, 163, 220 |
5 | 227, 165, 163, 110 |
11 | 227, 33, 163, 22 |
227, 3, 163, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 227 x 3 x 163 x 2 = 48841320
Therefore, the lowest common multiple of 454,660,163,440 is 48841320.
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.
454 x 660 x 163 x 440 = 21490180800
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.
454 : 1, 2, 227, 454
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
163 : 1, 163
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,660,163,440, is 1.
Now, the common factors can be found like this.
454:2x 227
660:2x 2x 3x 5x 11
163:163
440:2x 2x 2x 5x 11
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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 21490180800/(1x440)
LCM = 21490180800/440
LCM = 48841320
Thus, we can understand that the LCM of 454,660,163,440 is 48841320.
