Given numbers are 989, 506, 656, 765

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

Apply this formula for all numbers.

Step1:

LCM(989, 506) = 21758

GCD(989, 506) = ( 989 x 506 ) / 21758

= 989 / 506

= 989

Step2:

LCM(23, 656) = 15088

GCD(23, 656) = ( 23 x 656 ) / 15088

= 23 / 656

= 23

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 989, 506, 656, 765 is 1
