Given numbers are 398, 682, 403, 602
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 682) = 135718
GCD(398, 682) = ( 398 x 682 ) / 135718
= 398 / 682
= 398
Step2:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
Step3:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
So, Greatest Common Divisor of 398, 682, 403, 602 is 1
