Given numbers are 614,904,748,691,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 614,904,748,691,921 is 107584006728.
Find LCM of 614,904,748,691,921 with Prime Factorization
| 2 | 614, 904, 748, 691, 921 |
| 2 | 307, 452, 374, 691, 921 |
| 307 | 307, 226, 187, 691, 921 |
| 1, 226, 187, 691, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 307 x 1 x 226 x 187 x 691 x 3 = 107584006728
Therefore, the lowest common multiple of 614,904,748,691,921 is 107584006728.
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.
614 x 904 x 748 x 691 x 921 = 264226320523968
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.
614 : 1, 2, 307, 614
904 : 1, 2, 4, 8, 113, 226, 452, 904
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
691 : 1, 691
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 614,904,748,691,921, is 1.
Now, the common factors can be found like this.
614:2x 307
904:2x 2x 2x 113
748:2x 2x 11x 17
691:691
921:3x 307
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 307 = 2456
Therefore, the value for common factors is 2456.
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 = 264226320523968/(1x2456)
LCM = 264226320523968/2456
LCM = 107584006728
Thus, we can understand that the LCM of 614,904,748,691,921 is 107584006728.
