Given numbers are 197, 155, 203, 742
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(197, 155) = 30535
GCD(197, 155) = ( 197 x 155 ) / 30535
= 197 / 155
= 197
Step2:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
Step3:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
So, Greatest Common Divisor of 197, 155, 203, 742 is 1
