GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 660) = 258060
GCD(782, 660) = ( 782 x 660 ) / 258060
= 782 / 660
= 782
Step2:
LCM(2, 278) = 278
GCD(2, 278) = ( 2 x 278 ) / 278
= 2 / 278
= 2
Step3:
LCM(2, 192) = 192
GCD(2, 192) = ( 2 x 192 ) / 192
= 2 / 192
= 2
So, Greatest Common Divisor of 782, 660, 278, 192 is 2
