Given numbers are 520, 965, 309, 659

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

Apply this formula for all numbers.

Step1:

LCM(520, 965) = 100360

GCD(520, 965) = ( 520 x 965 ) / 100360

= 520 / 965

= 520

Step2:

LCM(5, 309) = 1545

GCD(5, 309) = ( 5 x 309 ) / 1545

= 5 / 309

= 5

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 520, 965, 309, 659 is 1
