Given numbers are 685, 945, 864, 259
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 945) = 129465
GCD(685, 945) = ( 685 x 945 ) / 129465
= 685 / 945
= 685
Step2:
LCM(5, 864) = 4320
GCD(5, 864) = ( 5 x 864 ) / 4320
= 5 / 864
= 5
Step3:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
So, Greatest Common Divisor of 685, 945, 864, 259 is 1
