Given numbers are 861, 231, 806, 498
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 231) = 9471
GCD(861, 231) = ( 861 x 231 ) / 9471
= 861 / 231
= 861
Step2:
LCM(21, 806) = 16926
GCD(21, 806) = ( 21 x 806 ) / 16926
= 21 / 806
= 21
Step3:
LCM(1, 498) = 498
GCD(1, 498) = ( 1 x 498 ) / 498
= 1 / 498
= 1
So, Greatest Common Divisor of 861, 231, 806, 498 is 1
