GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 556) = 218508
GCD(786, 556) = ( 786 x 556 ) / 218508
= 786 / 556
= 786
Step2:
LCM(2, 943) = 1886
GCD(2, 943) = ( 2 x 943 ) / 1886
= 2 / 943
= 2
Step3:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
So, Greatest Common Divisor of 786, 556, 943, 189 is 1
