Given numbers are 990, 261, 211, 882
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 261) = 28710
GCD(990, 261) = ( 990 x 261 ) / 28710
= 990 / 261
= 990
Step2:
LCM(9, 211) = 1899
GCD(9, 211) = ( 9 x 211 ) / 1899
= 9 / 211
= 9
Step3:
LCM(1, 882) = 882
GCD(1, 882) = ( 1 x 882 ) / 882
= 1 / 882
= 1
So, Greatest Common Divisor of 990, 261, 211, 882 is 1
