Given numbers are 485, 713, 401, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 713) = 345805
GCD(485, 713) = ( 485 x 713 ) / 345805
= 485 / 713
= 485
Step2:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 485, 713, 401, 639 is 1
