Given numbers are 804, 130, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(804, 130) = 52260
GCD(804, 130) = ( 804 x 130 ) / 52260
= 804 / 130
= 804
Step2:
LCM(2, 861) = 1722
GCD(2, 861) = ( 2 x 861 ) / 1722
= 2 / 861
= 2
So, Greatest Common Divisor of 804, 130, 861 is 1
