Given numbers are 126, 308, 423, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 308) = 2772
GCD(126, 308) = ( 126 x 308 ) / 2772
= 126 / 308
= 126
Step2:
LCM(14, 423) = 5922
GCD(14, 423) = ( 14 x 423 ) / 5922
= 14 / 423
= 14
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 126, 308, 423, 166 is 1
