Given numbers are 260,220,505,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,220,505,121 is 3177460.
Find LCM of 260,220,505,121 with Prime Factorization
| 2 | 260, 220, 505, 121 |
| 2 | 130, 110, 505, 121 |
| 5 | 65, 55, 505, 121 |
| 11 | 13, 11, 101, 121 |
| 13, 1, 101, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 13 x 1 x 101 x 11 = 3177460
Therefore, the lowest common multiple of 260,220,505,121 is 3177460.
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.
260 x 220 x 505 x 121 = 3495206000
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
505 : 1, 5, 101, 505
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,220,505,121, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
220:2x 2x 5x 11
505:5x 101
121:11x 11
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 5x 11 = 1100
Therefore, the value for common factors is 1100.
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 = 3495206000/(1x1100)
LCM = 3495206000/1100
LCM = 3177460
Thus, we can understand that the LCM of 260,220,505,121 is 3177460.
