GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 484) = 236676
GCD(978, 484) = ( 978 x 484 ) / 236676
= 978 / 484
= 978
Step2:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
Step3:
LCM(1, 539) = 539
GCD(1, 539) = ( 1 x 539 ) / 539
= 1 / 539
= 1
So, Greatest Common Divisor of 978, 484, 639, 539 is 1
