GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 999) = 70929
GCD(639, 999) = ( 639 x 999 ) / 70929
= 639 / 999
= 639
Step2:
LCM(9, 335) = 3015
GCD(9, 335) = ( 9 x 335 ) / 3015
= 9 / 335
= 9
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 639, 999, 335, 755 is 1
