Given numbers are 520, 821, 909, 183
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 821) = 426920
GCD(520, 821) = ( 520 x 821 ) / 426920
= 520 / 821
= 520
Step2:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
Step3:
LCM(1, 183) = 183
GCD(1, 183) = ( 1 x 183 ) / 183
= 1 / 183
= 1
So, Greatest Common Divisor of 520, 821, 909, 183 is 1
