Given numbers are 198, 195, 217, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 195) = 12870
GCD(198, 195) = ( 198 x 195 ) / 12870
= 198 / 195
= 198
Step2:
LCM(3, 217) = 651
GCD(3, 217) = ( 3 x 217 ) / 651
= 3 / 217
= 3
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 198, 195, 217, 307 is 1
