Given numbers are 36, 84, 51, 20
The list of prime factors of all numbers are
Prime factors of 36 are 2 x 2 x 3 x 3
Prime factors of 84 are 2 x 2 x 3 x 7
Prime factors of 51 are 3 x 17
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 36, 84, 51, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(36, 84) = 252
GCD(36, 84) = ( 36 x 84 ) / 252
= 36 / 84
= 36
Step2:
LCM(12, 51) = 204
GCD(12, 51) = ( 12 x 51 ) / 204
= 12 / 51
= 12
Step3:
LCM(3, 20) = 60
GCD(3, 20) = ( 3 x 20 ) / 60
= 3 / 20
= 3
So, Greatest Common Divisor of 36, 84, 51, 20 is 1
