Given numbers are 401,955,720,696
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,955,720,696 is 1599220080.
Find LCM of 401,955,720,696 with Prime Factorization
| 2 | 401, 955, 720, 696 |
| 2 | 401, 955, 360, 348 |
| 2 | 401, 955, 180, 174 |
| 3 | 401, 955, 90, 87 |
| 5 | 401, 955, 30, 29 |
| 401, 191, 6, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 401 x 191 x 6 x 29 = 1599220080
Therefore, the lowest common multiple of 401,955,720,696 is 1599220080.
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.
401 x 955 x 720 x 696 = 191906409600
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.
401 : 1, 401
955 : 1, 5, 191, 955
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
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,955,720,696, is 1.
Now, the common factors can be found like this.
401:401
955:5x 191
720:2x 2x 2x 2x 3x 3x 5
696:2x 2x 2x 3x 29
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 191906409600/(1x120)
LCM = 191906409600/120
LCM = 1599220080
Thus, we can understand that the LCM of 401,955,720,696 is 1599220080.
