Given numbers are 185,981,558,543,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 185,981,558,543,639 is 144600351570.
Find LCM of 185,981,558,543,639 with Prime Factorization
| 3 | 185, 981, 558, 543, 639 |
| 3 | 185, 327, 186, 181, 213 |
| 185, 109, 62, 181, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 185 x 109 x 62 x 181 x 71 = 144600351570
Therefore, the lowest common multiple of 185,981,558,543,639 is 144600351570.
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.
185 x 981 x 558 x 543 x 639 = 35137885431510
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.
185 : 1, 5, 37, 185
981 : 1, 3, 9, 109, 327, 981
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
543 : 1, 3, 181, 543
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,981,558,543,639, is 1.
Now, the common factors can be found like this.
185:5x 37
981:3x 3x 109
558:2x 3x 3x 31
543:3x 181
639:3x 3x 71
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 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 35137885431510/(1x243)
LCM = 35137885431510/243
LCM = 144600351570
Thus, we can understand that the LCM of 185,981,558,543,639 is 144600351570.
