Given numbers are 406, 485, 646, 275
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 485) = 196910
GCD(406, 485) = ( 406 x 485 ) / 196910
= 406 / 485
= 406
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
So, Greatest Common Divisor of 406, 485, 646, 275 is 1
