Given numbers are 455, 251, 646, 127
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 251) = 114205
GCD(455, 251) = ( 455 x 251 ) / 114205
= 455 / 251
= 455
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
So, Greatest Common Divisor of 455, 251, 646, 127 is 1
