The LCM of 216,320,639,71 is 613440.
Find LCM of 216,320,639,71 with Prime Factorization
| 2 | 216, 320, 639, 71 |
| 2 | 108, 160, 639, 71 |
| 2 | 54, 80, 639, 71 |
| 3 | 27, 40, 639, 71 |
| 3 | 9, 40, 213, 71 |
| 71 | 3, 40, 71, 71 |
| 3, 40, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 71 x 3 x 40 x 1 x 1 = 613440
Therefore, the lowest common multiple of 216,320,639,71 is 613440.
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.
216 x 320 x 639 x 71 = 3135905280
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
639 : 1, 3, 9, 71, 213, 639
71 : 1, 71
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,320,639,71, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
320:2x 2x 2x 2x 2x 2x 5
639:3x 3x 71
71:71
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 3x 3x 71 = 5112
Therefore, the value for common factors is 5112.
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 = 3135905280/(1x5112)
LCM = 3135905280/5112
LCM = 613440
Thus, we can understand that the LCM of 216,320,639,71 is 613440.
