Given numbers are 942, 980, 777, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(942, 980) = 461580
GCD(942, 980) = ( 942 x 980 ) / 461580
= 942 / 980
= 942
Step2:
LCM(2, 777) = 1554
GCD(2, 777) = ( 2 x 777 ) / 1554
= 2 / 777
= 2
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 942, 980, 777, 220 is 1
