Given numbers are 689, 969, 63, 617

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

Apply this formula for all numbers.

Step1:

LCM(689, 969) = 667641

GCD(689, 969) = ( 689 x 969 ) / 667641

= 689 / 969

= 689

Step2:

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

= 1 / 63

= 1

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 689, 969, 63, 617 is 1
