Given numbers are 904,502,780,902,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,502,780,902,781 is 1416810131880.
Find LCM of 904,502,780,902,781 with Prime Factorization
| 2 | 904, 502, 780, 902, 781 |
| 2 | 452, 251, 390, 451, 781 |
| 11 | 226, 251, 195, 451, 781 |
| 226, 251, 195, 41, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 226 x 251 x 195 x 41 x 71 = 1416810131880
Therefore, the lowest common multiple of 904,502,780,902,781 is 1416810131880.
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 502 x 780 x 902 x 781 = 249358583210880
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
502 : 1, 2, 251, 502
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
902 : 1, 2, 11, 22, 41, 82, 451, 902
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,502,780,902,781, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
502:2x 251
780:2x 2x 3x 5x 13
902:2x 11x 41
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 249358583210880/(1x176)
LCM = 249358583210880/176
LCM = 1416810131880
Thus, we can understand that the LCM of 904,502,780,902,781 is 1416810131880.
