if we list the prime factors of both numbers we get the following:
2187 : 3 3 3 3 3 3 3
135405: 3 3 3 5 17 59
We can then take the product of whatever factors they both share. Since they both have 3 3's the product is 27.
This means that 27 is the largest number that will divide both 2187 and 135405
The GCF is 27.
1024 = 2 to the power 10, 2187 = 3 to the power 7. There is no common factor above 1.
The greatest common factor of 192 and 2,187 is 3
The GCF is 27.
Prime factorization of 297891 = 33 x 11 x 17 x 59 Prime factorization of 2187 = 37 gcd(297891, 2187) = 33 = 27.
The Greatest Common Divisor of 297, 891, 2187 is 27.
The least common multiple of 135 , 405 , 2187 = 10,935
The Least Common Multiple (LCM) for 189 567 2187 is 15,309.
24,129,171
The exponential form of 2187 is 3^7. This is because 3 raised to the power of 7 equals 2187. In exponential form, the base (3) is raised to the power of the exponent (7) to give the result (2187).
The LCM is 24057.
A mathemtical trick is to note that all three numbers are divisible by '9'. How do we known this?? Because the sum of the digits in each number adds to '9'. Hence 189, 567, 2187) 189 ; 1 + 8 + 9 = 18 = 1 + 8 = 9 567 ; 5 + 6 + 7 = 18 = 1 + 8 = 9 2187 [ 2 + 1 + 8 + 7 = 18 = 1 + 8 = 9 189/9 = 21 567/ 9 = 63 2187/9 = 243 All three sub-answer will divide by '3' Hence 7,9,81 ( There are NO common factors ) Hence 9 x 3 = 27 is the GCF. NB THis mathemtical 'trick' can only be done with '9'. !!!!!
