Given numbers are 403, 341, 658, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 341) = 4433
GCD(403, 341) = ( 403 x 341 ) / 4433
= 403 / 341
= 403
Step2:
LCM(31, 658) = 20398
GCD(31, 658) = ( 31 x 658 ) / 20398
= 31 / 658
= 31
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 403, 341, 658, 390 is 1
