GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 817) = 129903
GCD(159, 817) = ( 159 x 817 ) / 129903
= 159 / 817
= 159
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 159, 817, 128, 439 is 1
