Given numbers are 861, 146, 161, 973
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 146) = 125706
GCD(861, 146) = ( 861 x 146 ) / 125706
= 861 / 146
= 861
Step2:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
Step3:
LCM(1, 973) = 973
GCD(1, 973) = ( 1 x 973 ) / 973
= 1 / 973
= 1
So, Greatest Common Divisor of 861, 146, 161, 973 is 1
