Given numbers are 861, 694, 121, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 694) = 597534
GCD(861, 694) = ( 861 x 694 ) / 597534
= 861 / 694
= 861
Step2:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 861, 694, 121, 166 is 1
