Given numbers are 777, 144, 682, 648

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

Apply this formula for all numbers.

Step1:

LCM(777, 144) = 37296

GCD(777, 144) = ( 777 x 144 ) / 37296

= 777 / 144

= 777

Step2:

LCM(3, 682) = 2046

GCD(3, 682) = ( 3 x 682 ) / 2046

= 3 / 682

= 3

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 777, 144, 682, 648 is 1
