Given numbers are 861, 985, 894, 172
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 985) = 848085
GCD(861, 985) = ( 861 x 985 ) / 848085
= 861 / 985
= 861
Step2:
LCM(1, 894) = 894
GCD(1, 894) = ( 1 x 894 ) / 894
= 1 / 894
= 1
Step3:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
So, Greatest Common Divisor of 861, 985, 894, 172 is 1
