Given numbers are 178, 686, 769, 877

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

Apply this formula for all numbers.

Step1:

LCM(178, 686) = 61054

GCD(178, 686) = ( 178 x 686 ) / 61054

= 178 / 686

= 178

Step2:

LCM(2, 769) = 1538

GCD(2, 769) = ( 2 x 769 ) / 1538

= 2 / 769

= 2

Step3:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

So, Greatest Common Divisor of 178, 686, 769, 877 is 1
