Given numbers are 969, 915, 487, 688

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

Apply this formula for all numbers.

Step1:

LCM(969, 915) = 295545

GCD(969, 915) = ( 969 x 915 ) / 295545

= 969 / 915

= 969

Step2:

LCM(3, 487) = 1461

GCD(3, 487) = ( 3 x 487 ) / 1461

= 3 / 487

= 3

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 969, 915, 487, 688 is 1
