Given numbers are 681,227,418,562
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,227,418,562 is 79988898.
Find LCM of 681,227,418,562 with Prime Factorization
| 2 | 681, 227, 418, 562 |
| 227 | 681, 227, 209, 281 |
| 3, 1, 209, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 227 x 3 x 1 x 209 x 281 = 79988898
Therefore, the lowest common multiple of 681,227,418,562 is 79988898.
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.
681 x 227 x 418 x 562 = 36314959692
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.
681 : 1, 3, 227, 681
227 : 1, 227
418 : 1, 2, 11, 19, 22, 38, 209, 418
562 : 1, 2, 281, 562
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,227,418,562, is 1.
Now, the common factors can be found like this.
681:3x 227
227:227
418:2x 11x 19
562:2x 281
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 227 = 454
Therefore, the value for common factors is 454.
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 = 36314959692/(1x454)
LCM = 36314959692/454
LCM = 79988898
Thus, we can understand that the LCM of 681,227,418,562 is 79988898.
