Given numbers are 220, 200, 656, 947
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 200) = 2200
GCD(220, 200) = ( 220 x 200 ) / 2200
= 220 / 200
= 220
Step2:
LCM(20, 656) = 3280
GCD(20, 656) = ( 20 x 656 ) / 3280
= 20 / 656
= 20
Step3:
LCM(4, 947) = 3788
GCD(4, 947) = ( 4 x 947 ) / 3788
= 4 / 947
= 4
So, Greatest Common Divisor of 220, 200, 656, 947 is 1
