Given numbers are 181, 643, 911, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(181, 643) = 116383
GCD(181, 643) = ( 181 x 643 ) / 116383
= 181 / 643
= 181
Step2:
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
= 1 / 911
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 181, 643, 911, 663 is 1
