Given numbers are 777, 715, 27, 255

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

Apply this formula for all numbers.

Step1:

LCM(777, 715) = 555555

GCD(777, 715) = ( 777 x 715 ) / 555555

= 777 / 715

= 777

Step2:

LCM(1, 27) = 27

GCD(1, 27) = ( 1 x 27 ) / 27

= 1 / 27

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 777, 715, 27, 255 is 1
