GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(442, 276) = 60996
GCD(442, 276) = ( 442 x 276 ) / 60996
= 442 / 276
= 442
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 339) = 678
GCD(2, 339) = ( 2 x 339 ) / 678
= 2 / 339
= 2
So, Greatest Common Divisor of 442, 276, 780, 339 is 1
