Given numbers are 765, 390, 177, 977

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

Apply this formula for all numbers.

Step1:

LCM(765, 390) = 19890

GCD(765, 390) = ( 765 x 390 ) / 19890

= 765 / 390

= 765

Step2:

LCM(15, 177) = 885

GCD(15, 177) = ( 15 x 177 ) / 885

= 15 / 177

= 15

Step3:

LCM(3, 977) = 2931

GCD(3, 977) = ( 3 x 977 ) / 2931

= 3 / 977

= 3

So, Greatest Common Divisor of 765, 390, 177, 977 is 1
