The LCM of 665,616,471,476 is 468569640.
Find LCM of 665,616,471,476 with Prime Factorization
| 2 | 665, 616, 471, 476 |
| 2 | 665, 308, 471, 238 |
| 7 | 665, 154, 471, 119 |
| 95, 22, 471, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 95 x 22 x 471 x 17 = 468569640
Therefore, the lowest common multiple of 665,616,471,476 is 468569640.
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.
665 x 616 x 471 x 476 = 91839649440
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
471 : 1, 3, 157, 471
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,616,471,476, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
616:2x 2x 2x 7x 11
471:3x 157
476:2x 2x 7x 17
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 91839649440/(1x196)
LCM = 91839649440/196
LCM = 468569640
Thus, we can understand that the LCM of 665,616,471,476 is 468569640.
