Given numbers are 121,813,990,724,625
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,813,990,724,625 is 133541347500.
Find LCM of 121,813,990,724,625 with Prime Factorization
| 2 | 121, 813, 990, 724, 625 |
| 3 | 121, 813, 495, 362, 625 |
| 5 | 121, 271, 165, 362, 625 |
| 11 | 121, 271, 33, 362, 125 |
| 11, 271, 3, 362, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 11 x 271 x 3 x 362 x 125 = 133541347500
Therefore, the lowest common multiple of 121,813,990,724,625 is 133541347500.
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.
121 x 813 x 990 x 724 x 625 = 44068644675000
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.
121 : 1, 11, 121
813 : 1, 3, 271, 813
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
724 : 1, 2, 4, 181, 362, 724
625 : 1, 5, 25, 125, 625
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,813,990,724,625, is 1.
Now, the common factors can be found like this.
121:11x 11
813:3x 271
990:2x 3x 3x 5x 11
724:2x 2x 181
625:5x 5x 5x 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 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 44068644675000/(1x330)
LCM = 44068644675000/330
LCM = 133541347500
Thus, we can understand that the LCM of 121,813,990,724,625 is 133541347500.
