Given numbers are 766,540,978,742,163
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,540,978,742,163 is 12507025860.
Find LCM of 766,540,978,742,163 with Prime Factorization
| 2 | 766, 540, 978, 742, 163 |
| 3 | 383, 270, 489, 371, 163 |
| 163 | 383, 90, 163, 371, 163 |
| 383, 90, 1, 371, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 383 x 90 x 1 x 371 x 1 = 12507025860
Therefore, the lowest common multiple of 766,540,978,742,163 is 12507025860.
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.
766 x 540 x 978 x 742 x 163 = 48927485164320
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.
766 : 1, 2, 383, 766
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
978 : 1, 2, 3, 6, 163, 326, 489, 978
742 : 1, 2, 7, 14, 53, 106, 371, 742
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,540,978,742,163, is 1.
Now, the common factors can be found like this.
766:2x 383
540:2x 2x 3x 3x 3x 5
978:2x 3x 163
742:2x 7x 53
163:163
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 3x 163 = 3912
Therefore, the value for common factors is 3912.
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 = 48927485164320/(1x3912)
LCM = 48927485164320/3912
LCM = 12507025860
Thus, we can understand that the LCM of 766,540,978,742,163 is 12507025860.
