Given numbers are 399, 820, 680, 500
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 820) = 327180
GCD(399, 820) = ( 399 x 820 ) / 327180
= 399 / 820
= 399
Step2:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
Step3:
LCM(1, 500) = 500
GCD(1, 500) = ( 1 x 500 ) / 500
= 1 / 500
= 1
So, Greatest Common Divisor of 399, 820, 680, 500 is 1
