Given numbers are 172,266,987,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,266,987,611 is 41931708.
Find LCM of 172,266,987,611 with Prime Factorization
| 2 | 172, 266, 987, 611 |
| 7 | 86, 133, 987, 611 |
| 47 | 86, 19, 141, 611 |
| 86, 19, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 47 x 86 x 19 x 3 x 13 = 41931708
Therefore, the lowest common multiple of 172,266,987,611 is 41931708.
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.
172 x 266 x 987 x 611 = 27591063864
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.
172 : 1, 2, 4, 43, 86, 172
266 : 1, 2, 7, 14, 19, 38, 133, 266
987 : 1, 3, 7, 21, 47, 141, 329, 987
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,266,987,611, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
266:2x 7x 19
987:3x 7x 47
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 47 = 658
Therefore, the value for common factors is 658.
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 = 27591063864/(1x658)
LCM = 27591063864/658
LCM = 41931708
Thus, we can understand that the LCM of 172,266,987,611 is 41931708.
