Given numbers are 274,978,706,788,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 274,978,706,788,261 is 1621248554124.
Find LCM of 274,978,706,788,261 with Prime Factorization
| 2 | 274, 978, 706, 788, 261 |
| 3 | 137, 489, 353, 394, 261 |
| 137, 163, 353, 394, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 163 x 353 x 394 x 87 = 1621248554124
Therefore, the lowest common multiple of 274,978,706,788,261 is 1621248554124.
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.
274 x 978 x 706 x 788 x 261 = 38909965298976
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.
274 : 1, 2, 137, 274
978 : 1, 2, 3, 6, 163, 326, 489, 978
706 : 1, 2, 353, 706
788 : 1, 2, 4, 197, 394, 788
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 274,978,706,788,261, is 1.
Now, the common factors can be found like this.
274:2x 137
978:2x 3x 163
706:2x 353
788:2x 2x 197
261:3x 3x 29
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 3 = 24
Therefore, the value for common factors is 24.
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 = 38909965298976/(1x24)
LCM = 38909965298976/24
LCM = 1621248554124
Thus, we can understand that the LCM of 274,978,706,788,261 is 1621248554124.
