Given numbers are 645, 812, 102, 229
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 812) = 523740
GCD(645, 812) = ( 645 x 812 ) / 523740
= 645 / 812
= 645
Step2:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
Step3:
LCM(1, 229) = 229
GCD(1, 229) = ( 1 x 229 ) / 229
= 1 / 229
= 1
So, Greatest Common Divisor of 645, 812, 102, 229 is 1
