Given numbers are 645, 276, 115, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 276) = 59340
GCD(645, 276) = ( 645 x 276 ) / 59340
= 645 / 276
= 645
Step2:
LCM(3, 115) = 345
GCD(3, 115) = ( 3 x 115 ) / 345
= 3 / 115
= 3
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 645, 276, 115, 122 is 1
