Given numbers are 389, 622, 821, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 622) = 241958
GCD(389, 622) = ( 389 x 622 ) / 241958
= 389 / 622
= 389
Step2:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 389, 622, 821, 520 is 1
