Given numbers are 398, 695, 773, 987

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

Apply this formula for all numbers.

Step1:

LCM(398, 695) = 276610

GCD(398, 695) = ( 398 x 695 ) / 276610

= 398 / 695

= 398

Step2:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 398, 695, 773, 987 is 1
