Given numbers are 775, 815, 969, 690

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

Apply this formula for all numbers.

Step1:

LCM(775, 815) = 126325

GCD(775, 815) = ( 775 x 815 ) / 126325

= 775 / 815

= 775

Step2:

LCM(5, 969) = 4845

GCD(5, 969) = ( 5 x 969 ) / 4845

= 5 / 969

= 5

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 775, 815, 969, 690 is 1
