Given numbers are 189,833,240,741,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,833,240,741,987 is 20887841520.
Find LCM of 189,833,240,741,987 with Prime Factorization
| 3 | 189, 833, 240, 741, 987 |
| 7 | 63, 833, 80, 247, 329 |
| 9, 119, 80, 247, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 9 x 119 x 80 x 247 x 47 = 20887841520
Therefore, the lowest common multiple of 189,833,240,741,987 is 20887841520.
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.
189 x 833 x 240 x 741 x 987 = 27634614330960
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
833 : 1, 7, 17, 49, 119, 833
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
741 : 1, 3, 13, 19, 39, 57, 247, 741
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,833,240,741,987, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
833:7x 7x 17
240:2x 2x 2x 2x 3x 5
741:3x 13x 19
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 7 = 1323
Therefore, the value for common factors is 1323.
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 = 27634614330960/(1x1323)
LCM = 27634614330960/1323
LCM = 20887841520
Thus, we can understand that the LCM of 189,833,240,741,987 is 20887841520.
