Given numbers are 639, 694, 916, 706
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 694) = 443466
GCD(639, 694) = ( 639 x 694 ) / 443466
= 639 / 694
= 639
Step2:
LCM(1, 916) = 916
GCD(1, 916) = ( 1 x 916 ) / 916
= 1 / 916
= 1
Step3:
LCM(1, 706) = 706
GCD(1, 706) = ( 1 x 706 ) / 706
= 1 / 706
= 1
So, Greatest Common Divisor of 639, 694, 916, 706 is 1
