GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 162) = 1134
GCD(189, 162) = ( 189 x 162 ) / 1134
= 189 / 162
= 189
Step2:
LCM(27, 781) = 21087
GCD(27, 781) = ( 27 x 781 ) / 21087
= 27 / 781
= 27
Step3:
LCM(1, 175) = 175
GCD(1, 175) = ( 1 x 175 ) / 175
= 1 / 175
= 1
So, Greatest Common Divisor of 189, 162, 781, 175 is 1
