Given numbers are 427, 171, 124, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 171) = 73017
GCD(427, 171) = ( 427 x 171 ) / 73017
= 427 / 171
= 427
Step2:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 427, 171, 124, 631 is 1
