GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 989) = 631971
GCD(639, 989) = ( 639 x 989 ) / 631971
= 639 / 989
= 639
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 510) = 510
GCD(1, 510) = ( 1 x 510 ) / 510
= 1 / 510
= 1
So, Greatest Common Divisor of 639, 989, 809, 510 is 1
