The LCM of 772,180,717,791,380 is 124783682940.
Find LCM of 772,180,717,791,380 with Prime Factorization
| 2 | 772, 180, 717, 791, 380 |
| 2 | 386, 90, 717, 791, 190 |
| 3 | 193, 45, 717, 791, 95 |
| 5 | 193, 15, 239, 791, 95 |
| 193, 3, 239, 791, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 193 x 3 x 239 x 791 x 19 = 124783682940
Therefore, the lowest common multiple of 772,180,717,791,380 is 124783682940.
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.
772 x 180 x 717 x 791 x 380 = 29948083905600
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.
772 : 1, 2, 4, 193, 386, 772
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
717 : 1, 3, 239, 717
791 : 1, 7, 113, 791
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,180,717,791,380, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
180:2x 2x 3x 3x 5
717:3x 239
791:7x 113
380:2x 2x 5x 19
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 29948083905600/(1x240)
LCM = 29948083905600/240
LCM = 124783682940
Thus, we can understand that the LCM of 772,180,717,791,380 is 124783682940.
