GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 225) = 110475
GCD(491, 225) = ( 491 x 225 ) / 110475
= 491 / 225
= 491
Step2:
LCM(1, 206) = 206
GCD(1, 206) = ( 1 x 206 ) / 206
= 1 / 206
= 1
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 491, 225, 206, 163 is 1
