Given numbers are 923,469,917,665,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,469,917,665,140 is 21549114860.
Find LCM of 923,469,917,665,140 with Prime Factorization
| 5 | 923, 469, 917, 665, 140 |
| 7 | 923, 469, 917, 133, 28 |
| 923, 67, 131, 19, 4 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 923 x 67 x 131 x 19 x 4 = 21549114860
Therefore, the lowest common multiple of 923,469,917,665,140 is 21549114860.
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.
923 x 469 x 917 x 665 x 140 = 36956731984900
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.
923 : 1, 13, 71, 923
469 : 1, 7, 67, 469
917 : 1, 7, 131, 917
665 : 1, 5, 7, 19, 35, 95, 133, 665
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,469,917,665,140, is 1.
Now, the common factors can be found like this.
923:13x 71
469:7x 67
917:7x 131
665:5x 7x 19
140:2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 7x 7 = 1715
Therefore, the value for common factors is 1715.
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 = 36956731984900/(1x1715)
LCM = 36956731984900/1715
LCM = 21549114860
Thus, we can understand that the LCM of 923,469,917,665,140 is 21549114860.
