Given numbers are 415, 821, 591, 818
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 821) = 340715
GCD(415, 821) = ( 415 x 821 ) / 340715
= 415 / 821
= 415
Step2:
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
= 1 / 591
= 1
Step3:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
So, Greatest Common Divisor of 415, 821, 591, 818 is 1
