Given numbers are 405, 768, 434, 977

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

Apply this formula for all numbers.

Step1:

LCM(405, 768) = 103680

GCD(405, 768) = ( 405 x 768 ) / 103680

= 405 / 768

= 405

Step2:

LCM(3, 434) = 1302

GCD(3, 434) = ( 3 x 434 ) / 1302

= 3 / 434

= 3

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 405, 768, 434, 977 is 1
