GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 492) = 42804
GCD(261, 492) = ( 261 x 492 ) / 42804
= 261 / 492
= 261
Step2:
LCM(3, 196) = 588
GCD(3, 196) = ( 3 x 196 ) / 588
= 3 / 196
= 3
Step3:
LCM(1, 117) = 117
GCD(1, 117) = ( 1 x 117 ) / 117
= 1 / 117
= 1
So, Greatest Common Divisor of 261, 492, 196, 117 is 1
