Given numbers are 243, 405, 898, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 405) = 1215
GCD(243, 405) = ( 243 x 405 ) / 1215
= 243 / 405
= 243
Step2:
LCM(81, 898) = 72738
GCD(81, 898) = ( 81 x 898 ) / 72738
= 81 / 898
= 81
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 243, 405, 898, 220 is 1
