Given numbers are 538,541,840,681,541
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,541,840,681,541 is 27749469720.
Find LCM of 538,541,840,681,541 with Prime Factorization
| 2 | 538, 541, 840, 681, 541 |
| 3 | 269, 541, 420, 681, 541 |
| 541 | 269, 541, 140, 227, 541 |
| 269, 1, 140, 227, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 541 x 269 x 1 x 140 x 227 x 1 = 27749469720
Therefore, the lowest common multiple of 538,541,840,681,541 is 27749469720.
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.
538 x 541 x 840 x 681 x 541 = 90074778711120
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.
538 : 1, 2, 269, 538
541 : 1, 541
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
681 : 1, 3, 227, 681
541 : 1, 541
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,541,840,681,541, is 1.
Now, the common factors can be found like this.
538:2x 269
541:541
840:2x 2x 2x 3x 5x 7
681:3x 227
541:541
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 541 = 3246
Therefore, the value for common factors is 3246.
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 = 90074778711120/(1x3246)
LCM = 90074778711120/3246
LCM = 27749469720
Thus, we can understand that the LCM of 538,541,840,681,541 is 27749469720.
