GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 887) = 566793
GCD(639, 887) = ( 639 x 887 ) / 566793
= 639 / 887
= 639
Step2:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 639, 887, 230, 287 is 1
