Given numbers are 904,755,540,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,755,540,781 is 14392299240.
Find LCM of 904,755,540,781 with Prime Factorization
| 2 | 904, 755, 540, 781 |
| 2 | 452, 755, 270, 781 |
| 5 | 226, 755, 135, 781 |
| 226, 151, 27, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 226 x 151 x 27 x 781 = 14392299240
Therefore, the lowest common multiple of 904,755,540,781 is 14392299240.
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.
904 x 755 x 540 x 781 = 287845984800
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
755 : 1, 5, 151, 755
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,755,540,781, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
755:5x 151
540:2x 2x 3x 3x 3x 5
781:11x 71
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 5 = 20
Therefore, the value for common factors is 20.
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 = 287845984800/(1x20)
LCM = 287845984800/20
LCM = 14392299240
Thus, we can understand that the LCM of 904,755,540,781 is 14392299240.
