Given numbers are 403, 523, 420, 958
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 523) = 210769
GCD(403, 523) = ( 403 x 523 ) / 210769
= 403 / 523
= 403
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 958) = 958
GCD(1, 958) = ( 1 x 958 ) / 958
= 1 / 958
= 1
So, Greatest Common Divisor of 403, 523, 420, 958 is 1
