Given numbers are 285, 305, 956, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 305) = 17385
GCD(285, 305) = ( 285 x 305 ) / 17385
= 285 / 305
= 285
Step2:
LCM(5, 956) = 4780
GCD(5, 956) = ( 5 x 956 ) / 4780
= 5 / 956
= 5
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 285, 305, 956, 153 is 1
