Given numbers are 655,551,656,522
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,551,656,522 is 2130783120.
Find LCM of 655,551,656,522 with Prime Factorization
| 2 | 655, 551, 656, 522 |
| 29 | 655, 551, 328, 261 |
| 655, 19, 328, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 655 x 19 x 328 x 9 = 2130783120
Therefore, the lowest common multiple of 655,551,656,522 is 2130783120.
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.
655 x 551 x 656 x 522 = 123585420960
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.
655 : 1, 5, 131, 655
551 : 1, 19, 29, 551
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,551,656,522, is 1.
Now, the common factors can be found like this.
655:5x 131
551:19x 29
656:2x 2x 2x 2x 41
522:2x 3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 29 = 58
Therefore, the value for common factors is 58.
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 = 123585420960/(1x58)
LCM = 123585420960/58
LCM = 2130783120
Thus, we can understand that the LCM of 655,551,656,522 is 2130783120.
