Given numbers are 437, 195, 813, 243
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(437, 195) = 85215
GCD(437, 195) = ( 437 x 195 ) / 85215
= 437 / 195
= 437
Step2:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
Step3:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
So, Greatest Common Divisor of 437, 195, 813, 243 is 1
