Given numbers are 198, 161, 36, 400
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 161) = 31878
GCD(198, 161) = ( 198 x 161 ) / 31878
= 198 / 161
= 198
Step2:
LCM(1, 36) = 36
GCD(1, 36) = ( 1 x 36 ) / 36
= 1 / 36
= 1
Step3:
LCM(1, 400) = 400
GCD(1, 400) = ( 1 x 400 ) / 400
= 1 / 400
= 1
So, Greatest Common Divisor of 198, 161, 36, 400 is 1
