Given numbers are 938, 422, 646, 955
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(938, 422) = 197918
GCD(938, 422) = ( 938 x 422 ) / 197918
= 938 / 422
= 938
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 955) = 1910
GCD(2, 955) = ( 2 x 955 ) / 1910
= 2 / 955
= 2
So, Greatest Common Divisor of 938, 422, 646, 955 is 1
