Find LCM of 252,989,855,911,161 with Prime Factorization
| 3 | 252, 989, 855, 911, 161 |
| 3 | 84, 989, 285, 911, 161 |
| 7 | 28, 989, 95, 911, 161 |
| 23 | 4, 989, 95, 911, 23 |
| 4, 43, 95, 911, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 23 x 4 x 43 x 95 x 911 x 1 = 21569437260
Therefore, the lowest common multiple of 252,989,855,911,161 is 21569437260.
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.
252 x 989 x 855 x 911 x 161 = 31254114589740
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
989 : 1, 23, 43, 989
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
911 : 1, 911
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,989,855,911,161, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
989:23x 43
855:3x 3x 5x 19
911:911
161:7x 23
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 7x 23 = 1449
Therefore, the value for common factors is 1449.
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 = 31254114589740/(1x1449)
LCM = 31254114589740/1449
LCM = 21569437260
Thus, we can understand that the LCM of 252,989,855,911,161 is 21569437260.
