Given numbers are 212,254,478,646,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,254,478,646,442 is 27019876364.
Find LCM of 212,254,478,646,442 with Prime Factorization
| 2 | 212, 254, 478, 646, 442 |
| 17 | 106, 127, 239, 323, 221 |
| 106, 127, 239, 19, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 106 x 127 x 239 x 19 x 13 = 27019876364
Therefore, the lowest common multiple of 212,254,478,646,442 is 27019876364.
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 254 x 478 x 646 x 442 = 7349406371008
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
254 : 1, 2, 127, 254
478 : 1, 2, 239, 478
646 : 1, 2, 17, 19, 34, 38, 323, 646
442 : 1, 2, 13, 17, 26, 34, 221, 442
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,254,478,646,442, is 2.
Now, the common factors can be found like this.
212:2x 2x 53
254:2x 127
478:2x 239
646:2x 17x 19
442:2x 13x 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 2x 17 = 136
Therefore, the value for common factors is 136.
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 = 7349406371008/(2x136)
LCM = 7349406371008/272
LCM = 27019876364
Thus, we can understand that the LCM of 212,254,478,646,442 is 27019876364.
