Given numbers are 958, 390, 817, 521

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

Apply this formula for all numbers.

Step1:

LCM(958, 390) = 186810

GCD(958, 390) = ( 958 x 390 ) / 186810

= 958 / 390

= 958

Step2:

LCM(2, 817) = 1634

GCD(2, 817) = ( 2 x 817 ) / 1634

= 2 / 817

= 2

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 958, 390, 817, 521 is 1
