Given numbers are 401, 554, 897, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 554) = 222154
GCD(401, 554) = ( 401 x 554 ) / 222154
= 401 / 554
= 401
Step2:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 401, 554, 897, 247 is 1
