GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(994, 539) = 76538
GCD(994, 539) = ( 994 x 539 ) / 76538
= 994 / 539
= 994
Step2:
LCM(7, 858) = 6006
GCD(7, 858) = ( 7 x 858 ) / 6006
= 7 / 858
= 7
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 994, 539, 858, 639 is 1
