Given numbers are 415,136,120,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 415,136,120,505 is 17101320.
Find LCM of 415,136,120,505 with Prime Factorization
| 2 | 415, 136, 120, 505 |
| 2 | 415, 68, 60, 505 |
| 2 | 415, 34, 30, 505 |
| 5 | 415, 17, 15, 505 |
| 83, 17, 3, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 83 x 17 x 3 x 101 = 17101320
Therefore, the lowest common multiple of 415,136,120,505 is 17101320.
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.
415 x 136 x 120 x 505 = 3420264000
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.
415 : 1, 5, 83, 415
136 : 1, 2, 4, 8, 17, 34, 68, 136
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,136,120,505, is 1.
Now, the common factors can be found like this.
415:5x 83
136:2x 2x 2x 17
120:2x 2x 2x 3x 5
505:5x 101
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 2x 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 3420264000/(1x200)
LCM = 3420264000/200
LCM = 17101320
Thus, we can understand that the LCM of 415,136,120,505 is 17101320.
