Given numbers are 394, 654, 163, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 654) = 128838
GCD(394, 654) = ( 394 x 654 ) / 128838
= 394 / 654
= 394
Step2:
LCM(2, 163) = 326
GCD(2, 163) = ( 2 x 163 ) / 326
= 2 / 163
= 2
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 394, 654, 163, 231 is 1
