Find LCM of 212,170,536,391,360 with Prime Factorization
| 2 | 212, 170, 536, 391, 360 |
| 2 | 106, 85, 268, 391, 180 |
| 2 | 53, 85, 134, 391, 90 |
| 5 | 53, 85, 67, 391, 45 |
| 17 | 53, 17, 67, 391, 9 |
| 53, 1, 67, 23, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 53 x 1 x 67 x 23 x 9 = 499838760
Therefore, the lowest common multiple of 212,170,536,391,360 is 499838760.
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.
212 x 170 x 536 x 391 x 360 = 2719122854400
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.
212 : 1, 2, 4, 53, 106, 212
170 : 1, 2, 5, 10, 17, 34, 85, 170
536 : 1, 2, 4, 8, 67, 134, 268, 536
391 : 1, 17, 23, 391
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,170,536,391,360, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
170:2x 5x 17
536:2x 2x 2x 67
391:17x 23
360:2x 2x 2x 3x 3x 5
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 2x 2x 2x 5x 17 = 5440
Therefore, the value for common factors is 5440.
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 = 2719122854400/(1x5440)
LCM = 2719122854400/5440
LCM = 499838760
Thus, we can understand that the LCM of 212,170,536,391,360 is 499838760.
