Given numbers are 920, 942, 765, 238
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 942) = 433320
GCD(920, 942) = ( 920 x 942 ) / 433320
= 920 / 942
= 920
Step2:
LCM(2, 765) = 1530
GCD(2, 765) = ( 2 x 765 ) / 1530
= 2 / 765
= 2
Step3:
LCM(1, 238) = 238
GCD(1, 238) = ( 1 x 238 ) / 238
= 1 / 238
= 1
So, Greatest Common Divisor of 920, 942, 765, 238 is 1
