Given numbers are 181, 391, 237, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(181, 391) = 70771
GCD(181, 391) = ( 181 x 391 ) / 70771
= 181 / 391
= 181
Step2:
LCM(1, 237) = 237
GCD(1, 237) = ( 1 x 237 ) / 237
= 1 / 237
= 1
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 181, 391, 237, 423 is 1
