Given numbers are 765, 545, 215, 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, 545) = 83385

GCD(765, 545) = ( 765 x 545 ) / 83385

= 765 / 545

= 765

Step2:

LCM(5, 215) = 215

GCD(5, 215) = ( 5 x 215 ) / 215

= 5 / 215

= 5

Step3:

LCM(5, 977) = 4885

GCD(5, 977) = ( 5 x 977 ) / 4885

= 5 / 977

= 5

So, Greatest Common Divisor of 765, 545, 215, 977 is 1
