Given numbers are 655,917,467,427,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,917,467,427,981 is 128131249995.
Find LCM of 655,917,467,427,981 with Prime Factorization
| 7 | 655, 917, 467, 427, 981 |
| 131 | 655, 131, 467, 61, 981 |
| 5, 1, 467, 61, 981 |
Multiply the prime numbers at the bottom and the left side.
7 x 131 x 5 x 1 x 467 x 61 x 981 = 128131249995
Therefore, the lowest common multiple of 655,917,467,427,981 is 128131249995.
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 917 x 467 x 427 x 981 = 117496356245415
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
917 : 1, 7, 131, 917
467 : 1, 467
427 : 1, 7, 61, 427
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,917,467,427,981, is 1.
Now, the common factors can be found like this.
655:5x 131
917:7x 131
467:467
427:7x 61
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 131 = 917
Therefore, the value for common factors is 917.
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 = 117496356245415/(1x917)
LCM = 117496356245415/917
LCM = 128131249995
Thus, we can understand that the LCM of 655,917,467,427,981 is 128131249995.
