Find LCM of 118,342,385,360,665 with Prime Factorization
| 2 | 118, 342, 385, 360, 665 |
| 3 | 59, 171, 385, 180, 665 |
| 3 | 59, 57, 385, 60, 665 |
| 5 | 59, 19, 385, 20, 665 |
| 7 | 59, 19, 77, 4, 133 |
| 19 | 59, 19, 11, 4, 19 |
| 59, 1, 11, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 19 x 59 x 1 x 11 x 4 x 1 = 31074120
Therefore, the lowest common multiple of 118,342,385,360,665 is 31074120.
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.
118 x 342 x 385 x 360 x 665 = 3719572164000
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.
118 : 1, 2, 59, 118
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
385 : 1, 5, 7, 11, 35, 55, 77, 385
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,342,385,360,665, is 1.
Now, the common factors can be found like this.
118:2x 59
342:2x 3x 3x 19
385:5x 7x 11
360:2x 2x 2x 3x 3x 5
665:5x 7x 19
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 3x 3x 5x 5x 7x 19 = 119700
Therefore, the value for common factors is 119700.
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 = 3719572164000/(1x119700)
LCM = 3719572164000/119700
LCM = 31074120
Thus, we can understand that the LCM of 118,342,385,360,665 is 31074120.
