Given numbers are 212,478,838,272,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,478,838,272,155 is 223763061680.
Find LCM of 212,478,838,272,155 with Prime Factorization
| 2 | 212, 478, 838, 272, 155 |
| 2 | 106, 239, 419, 136, 155 |
| 53, 239, 419, 68, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 53 x 239 x 419 x 68 x 155 = 223763061680
Therefore, the lowest common multiple of 212,478,838,272,155 is 223763061680.
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 478 x 838 x 272 x 155 = 3580208986880
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
478 : 1, 2, 239, 478
838 : 1, 2, 419, 838
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,478,838,272,155, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
478:2x 239
838:2x 419
272:2x 2x 2x 2x 17
155:5x 31
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 2 = 16
Therefore, the value for common factors is 16.
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 = 3580208986880/(1x16)
LCM = 3580208986880/16
LCM = 223763061680
Thus, we can understand that the LCM of 212,478,838,272,155 is 223763061680.
