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

Apply this formula for all numbers.

Step1:

LCM(989, 729) = 720981

GCD(989, 729) = ( 989 x 729 ) / 720981

= 989 / 729

= 989

Step2:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 989, 729, 565, 162 is 1
