Given numbers are 543, 657, 769, 765

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

Apply this formula for all numbers.

Step1:

LCM(543, 657) = 118917

GCD(543, 657) = ( 543 x 657 ) / 118917

= 543 / 657

= 543

Step2:

LCM(3, 769) = 2307

GCD(3, 769) = ( 3 x 769 ) / 2307

= 3 / 769

= 3

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 543, 657, 769, 765 is 1
