Given numbers are 220, 286, 561, 982
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 286) = 2860
GCD(220, 286) = ( 220 x 286 ) / 2860
= 220 / 286
= 220
Step2:
LCM(22, 561) = 1122
GCD(22, 561) = ( 22 x 561 ) / 1122
= 22 / 561
= 22
Step3:
LCM(11, 982) = 10802
GCD(11, 982) = ( 11 x 982 ) / 10802
= 11 / 982
= 11
So, Greatest Common Divisor of 220, 286, 561, 982 is 1
