Given numbers are 172, 178, 471, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 178) = 15308
GCD(172, 178) = ( 172 x 178 ) / 15308
= 172 / 178
= 172
Step2:
LCM(2, 471) = 942
GCD(2, 471) = ( 2 x 471 ) / 942
= 2 / 471
= 2
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 172, 178, 471, 805 is 1
