Given numbers are 26, 53, 65, 20
The list of prime factors of all numbers are
Prime factors of 26 are 2 x 13
Prime factors of 53 are 53
Prime factors of 65 are 5 x 13
Prime factors of 20 are 2 x 2 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 26, 53, 65, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(26, 53) = 1378
GCD(26, 53) = ( 26 x 53 ) / 1378
= 26 / 53
= 26
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
So, Greatest Common Divisor of 26, 53, 65, 20 is 1
