Given numbers are 815, 887, 254, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 887) = 722905
GCD(815, 887) = ( 815 x 887 ) / 722905
= 815 / 887
= 815
Step2:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 815, 887, 254, 961 is 1
