Given numbers are 542,813,910,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,813,910,720 is 17755920.
Find LCM of 542,813,910,720 with Prime Factorization
| 2 | 542, 813, 910, 720 |
| 3 | 271, 813, 455, 360 |
| 5 | 271, 271, 455, 120 |
| 271 | 271, 271, 91, 24 |
| 1, 1, 91, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 271 x 1 x 1 x 91 x 24 = 17755920
Therefore, the lowest common multiple of 542,813,910,720 is 17755920.
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.
542 x 813 x 910 x 720 = 288711259200
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.
542 : 1, 2, 271, 542
813 : 1, 3, 271, 813
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,813,910,720, is 1.
Now, the common factors can be found like this.
542:2x 271
813:3x 271
910:2x 5x 7x 13
720:2x 2x 2x 2x 3x 3x 5
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 3x 5x 271 = 16260
Therefore, the value for common factors is 16260.
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 = 288711259200/(1x16260)
LCM = 288711259200/16260
LCM = 17755920
Thus, we can understand that the LCM of 542,813,910,720 is 17755920.
