Given numbers are 789,541,711,980,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,541,711,980,168 is 198279897480.
Find LCM of 789,541,711,980,168 with Prime Factorization
| 2 | 789, 541, 711, 980, 168 |
| 2 | 789, 541, 711, 490, 84 |
| 3 | 789, 541, 711, 245, 42 |
| 7 | 263, 541, 237, 245, 14 |
| 263, 541, 237, 35, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 263 x 541 x 237 x 35 x 2 = 198279897480
Therefore, the lowest common multiple of 789,541,711,980,168 is 198279897480.
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.
789 x 541 x 711 x 980 x 168 = 49966534164960
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.
789 : 1, 3, 263, 789
541 : 1, 541
711 : 1, 3, 9, 79, 237, 711
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,541,711,980,168, is 1.
Now, the common factors can be found like this.
789:3x 263
541:541
711:3x 3x 79
980:2x 2x 5x 7x 7
168:2x 2x 2x 3x 7
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 49966534164960/(1x252)
LCM = 49966534164960/252
LCM = 198279897480
Thus, we can understand that the LCM of 789,541,711,980,168 is 198279897480.
