GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 198) = 136818
GCD(691, 198) = ( 691 x 198 ) / 136818
= 691 / 198
= 691
Step2:
LCM(1, 239) = 239
GCD(1, 239) = ( 1 x 239 ) / 239
= 1 / 239
= 1
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 691, 198, 239, 158 is 1
