Given numbers are 646, 361, 905, 437
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 361) = 12274
GCD(646, 361) = ( 646 x 361 ) / 12274
= 646 / 361
= 646
Step2:
LCM(19, 905) = 17195
GCD(19, 905) = ( 19 x 905 ) / 17195
= 19 / 905
= 19
Step3:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
So, Greatest Common Divisor of 646, 361, 905, 437 is 1
