Given numbers are 399, 699, 985, 965

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(399, 699) = 92967

GCD(399, 699) = ( 399 x 699 ) / 92967

= 399 / 699

= 399

Step2:

LCM(3, 985) = 2955

GCD(3, 985) = ( 3 x 985 ) / 2955

= 3 / 985

= 3

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 399, 699, 985, 965 is 1
