Given numbers are 995, 980, 479, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(995, 980) = 195020
GCD(995, 980) = ( 995 x 980 ) / 195020
= 995 / 980
= 995
Step2:
LCM(5, 479) = 2395
GCD(5, 479) = ( 5 x 479 ) / 2395
= 5 / 479
= 5
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 995, 980, 479, 220 is 1
