Given numbers are 644, 401, 873, 922
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 401) = 258244
GCD(644, 401) = ( 644 x 401 ) / 258244
= 644 / 401
= 644
Step2:
LCM(1, 873) = 873
GCD(1, 873) = ( 1 x 873 ) / 873
= 1 / 873
= 1
Step3:
LCM(1, 922) = 922
GCD(1, 922) = ( 1 x 922 ) / 922
= 1 / 922
= 1
So, Greatest Common Divisor of 644, 401, 873, 922 is 1
