Given numbers are 201, 156, 172
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(201, 156) = 10452
GCD(201, 156) = ( 201 x 156 ) / 10452
= 201 / 156
= 201
Step2:
LCM(3, 172) = 516
GCD(3, 172) = ( 3 x 172 ) / 516
= 3 / 172
= 3
So, Greatest Common Divisor of 201, 156, 172 is 1
