GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 194) = 49858
GCD(257, 194) = ( 257 x 194 ) / 49858
= 257 / 194
= 257
Step2:
LCM(1, 434) = 434
GCD(1, 434) = ( 1 x 434 ) / 434
= 1 / 434
= 1
Step3:
LCM(1, 239) = 239
GCD(1, 239) = ( 1 x 239 ) / 239
= 1 / 239
= 1
So, Greatest Common Divisor of 257, 194, 434, 239 is 1
