Given numbers are 639, 439, 739, 993
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 439) = 280521
GCD(639, 439) = ( 639 x 439 ) / 280521
= 639 / 439
= 639
Step2:
LCM(1, 739) = 739
GCD(1, 739) = ( 1 x 739 ) / 739
= 1 / 739
= 1
Step3:
LCM(1, 993) = 993
GCD(1, 993) = ( 1 x 993 ) / 993
= 1 / 993
= 1
So, Greatest Common Divisor of 639, 439, 739, 993 is 1
