GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 739) = 475177
GCD(643, 739) = ( 643 x 739 ) / 475177
= 643 / 739
= 643
Step2:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 643, 739, 187, 842 is 1
