Given numbers are 605,121,625,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,121,625,425 is 1285625.
Find LCM of 605,121,625,425 with Prime Factorization
| 5 | 605, 121, 625, 425 |
| 5 | 121, 121, 125, 85 |
| 11 | 121, 121, 25, 17 |
| 11 | 11, 11, 25, 17 |
| 1, 1, 25, 17 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 11 x 11 x 1 x 1 x 25 x 17 = 1285625
Therefore, the lowest common multiple of 605,121,625,425 is 1285625.
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.
605 x 121 x 625 x 425 = 19445078125
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.
605 : 1, 5, 11, 55, 121, 605
121 : 1, 11, 121
625 : 1, 5, 25, 125, 625
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,121,625,425, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
121:11x 11
625:5x 5x 5x 5
425:5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5x 11x 11 = 15125
Therefore, the value for common factors is 15125.
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 = 19445078125/(1x15125)
LCM = 19445078125/15125
LCM = 1285625
Thus, we can understand that the LCM of 605,121,625,425 is 1285625.
