Given numbers are 69, 24, 77, 81
The list of prime factors of all numbers are
Prime factors of 69 are 3 x 23
Prime factors of 24 are 2 x 2 x 2 x 3
Prime factors of 77 are 7 x 11
Prime factors of 81 are 3 x 3 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 69, 24, 77, 81
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(69, 24) = 552
GCD(69, 24) = ( 69 x 24 ) / 552
= 69 / 24
= 69
Step2:
LCM(3, 77) = 231
GCD(3, 77) = ( 3 x 77 ) / 231
= 3 / 77
= 3
Step3:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
So, Greatest Common Divisor of 69, 24, 77, 81 is 1
