Given numbers are 610, 990, 71, 521

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

Apply this formula for all numbers.

Step1:

LCM(610, 990) = 60390

GCD(610, 990) = ( 610 x 990 ) / 60390

= 610 / 990

= 610

Step2:

LCM(10, 71) = 710

GCD(10, 71) = ( 10 x 71 ) / 710

= 10 / 71

= 10

Step3:

LCM(1, 521) = 521

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

= 1 / 521

= 1

So, Greatest Common Divisor of 610, 990, 71, 521 is 1
