Given numbers are 774, 669, 705, 505

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

Apply this formula for all numbers.

Step1:

LCM(774, 669) = 172602

GCD(774, 669) = ( 774 x 669 ) / 172602

= 774 / 669

= 774

Step2:

LCM(3, 705) = 705

GCD(3, 705) = ( 3 x 705 ) / 705

= 3 / 705

= 3

Step3:

LCM(3, 505) = 1515

GCD(3, 505) = ( 3 x 505 ) / 1515

= 3 / 505

= 3

So, Greatest Common Divisor of 774, 669, 705, 505 is 1
