Given numbers are 212,687,726,655,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,687,726,655,220 is 11543015220.
Find LCM of 212,687,726,655,220 with Prime Factorization
| 2 | 212, 687, 726, 655, 220 |
| 2 | 106, 687, 363, 655, 110 |
| 3 | 53, 687, 363, 655, 55 |
| 5 | 53, 229, 121, 655, 55 |
| 11 | 53, 229, 121, 131, 11 |
| 53, 229, 1, 131, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 53 x 229 x 1 x 131 x 11 = 11543015220
Therefore, the lowest common multiple of 212,687,726,655,220 is 11543015220.
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 687 x 726 x 655 x 220 = 15236780090400
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
687 : 1, 3, 229, 687
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
655 : 1, 5, 131, 655
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,687,726,655,220, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
687:3x 229
726:2x 3x 11x 11
655:5x 131
220:2x 2x 5x 11
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 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 15236780090400/(1x1320)
LCM = 15236780090400/1320
LCM = 11543015220
Thus, we can understand that the LCM of 212,687,726,655,220 is 11543015220.
