Given numbers are 861, 781, 250, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 781) = 672441
GCD(861, 781) = ( 861 x 781 ) / 672441
= 861 / 781
= 861
Step2:
LCM(1, 250) = 250
GCD(1, 250) = ( 1 x 250 ) / 250
= 1 / 250
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 861, 781, 250, 231 is 1
