Given numbers are 125,700,988,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 125,700,988,261 is 225634500.
Find LCM of 125,700,988,261 with Prime Factorization
| 2 | 125, 700, 988, 261 |
| 2 | 125, 350, 494, 261 |
| 5 | 125, 175, 247, 261 |
| 5 | 25, 35, 247, 261 |
| 5, 7, 247, 261 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 5 x 7 x 247 x 261 = 225634500
Therefore, the lowest common multiple of 125,700,988,261 is 225634500.
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.
125 x 700 x 988 x 261 = 22563450000
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.
125 : 1, 5, 25, 125
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 125,700,988,261, is 1.
Now, the common factors can be found like this.
125:5x 5x 5
700:2x 2x 5x 5x 7
988:2x 2x 13x 19
261:3x 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 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 22563450000/(1x100)
LCM = 22563450000/100
LCM = 225634500
Thus, we can understand that the LCM of 125,700,988,261 is 225634500.
