GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 505) = 95445
GCD(189, 505) = ( 189 x 505 ) / 95445
= 189 / 505
= 189
Step2:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 189, 505, 863, 439 is 1
