Given numbers are 438,425,120,925
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,425,120,925 is 27550200.
Find LCM of 438,425,120,925 with Prime Factorization
| 2 | 438, 425, 120, 925 |
| 3 | 219, 425, 60, 925 |
| 5 | 73, 425, 20, 925 |
| 5 | 73, 85, 4, 185 |
| 73, 17, 4, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 73 x 17 x 4 x 37 = 27550200
Therefore, the lowest common multiple of 438,425,120,925 is 27550200.
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.
438 x 425 x 120 x 925 = 20662650000
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
425 : 1, 5, 17, 25, 85, 425
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
925 : 1, 5, 25, 37, 185, 925
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,425,120,925, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
425:5x 5x 17
120:2x 2x 2x 3x 5
925:5x 5x 37
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 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 20662650000/(1x750)
LCM = 20662650000/750
LCM = 27550200
Thus, we can understand that the LCM of 438,425,120,925 is 27550200.
