Given numbers are 783,221,904,962,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,221,904,962,988 is 109970903016.
Find LCM of 783,221,904,962,988 with Prime Factorization
| 2 | 783, 221, 904, 962, 988 |
| 2 | 783, 221, 452, 481, 494 |
| 13 | 783, 221, 226, 481, 247 |
| 783, 17, 226, 37, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 783 x 17 x 226 x 37 x 19 = 109970903016
Therefore, the lowest common multiple of 783,221,904,962,988 is 109970903016.
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.
783 x 221 x 904 x 962 x 988 = 148680660877632
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
221 : 1, 13, 17, 221
904 : 1, 2, 4, 8, 113, 226, 452, 904
962 : 1, 2, 13, 26, 37, 74, 481, 962
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,221,904,962,988, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
221:13x 17
904:2x 2x 2x 113
962:2x 13x 37
988:2x 2x 13x 19
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 13x 13 = 1352
Therefore, the value for common factors is 1352.
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 = 148680660877632/(1x1352)
LCM = 148680660877632/1352
LCM = 109970903016
Thus, we can understand that the LCM of 783,221,904,962,988 is 109970903016.
