Given numbers are 769,386,922,254,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,386,922,254,405 is 7038389780190.
Find LCM of 769,386,922,254,405 with Prime Factorization
| 2 | 769, 386, 922, 254, 405 |
| 769, 193, 461, 127, 405 |
Multiply the prime numbers at the bottom and the left side.
2 x 769 x 193 x 461 x 127 x 405 = 7038389780190
Therefore, the lowest common multiple of 769,386,922,254,405 is 7038389780190.
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.
769 x 386 x 922 x 254 x 405 = 28153559120760
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.
769 : 1, 769
386 : 1, 2, 193, 386
922 : 1, 2, 461, 922
254 : 1, 2, 127, 254
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,386,922,254,405, is 1.
Now, the common factors can be found like this.
769:769
386:2x 193
922:2x 461
254:2x 127
405:3x 3x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 28153559120760/(1x4)
LCM = 28153559120760/4
LCM = 7038389780190
Thus, we can understand that the LCM of 769,386,922,254,405 is 7038389780190.
