Given numbers are 605, 306, 965, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 306) = 185130
GCD(605, 306) = ( 605 x 306 ) / 185130
= 605 / 306
= 605
Step2:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 605, 306, 965, 153 is 1
