Given numbers are 988,221,969,283
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,221,969,283 is 14259804.
Find LCM of 988,221,969,283 with Prime Factorization
| 13 | 988, 221, 969, 283 |
| 17 | 76, 17, 969, 283 |
| 19 | 76, 1, 57, 283 |
| 4, 1, 3, 283 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 19 x 4 x 1 x 3 x 283 = 14259804
Therefore, the lowest common multiple of 988,221,969,283 is 14259804.
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.
988 x 221 x 969 x 283 = 59876916996
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
221 : 1, 13, 17, 221
969 : 1, 3, 17, 19, 51, 57, 323, 969
283 : 1, 283
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,221,969,283, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
221:13x 17
969:3x 17x 19
283:283
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17x 19 = 4199
Therefore, the value for common factors is 4199.
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 = 59876916996/(1x4199)
LCM = 59876916996/4199
LCM = 14259804
Thus, we can understand that the LCM of 988,221,969,283 is 14259804.
