GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(177, 999) = 58941
GCD(177, 999) = ( 177 x 999 ) / 58941
= 177 / 999
= 177
Step2:
LCM(3, 207) = 207
GCD(3, 207) = ( 3 x 207 ) / 207
= 3 / 207
= 3
Step3:
LCM(3, 643) = 1929
GCD(3, 643) = ( 3 x 643 ) / 1929
= 3 / 643
= 3
So, Greatest Common Divisor of 177, 999, 207, 643 is 1
