Given numbers are 693, 781, 173, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 781) = 49203
GCD(693, 781) = ( 693 x 781 ) / 49203
= 693 / 781
= 693
Step2:
LCM(11, 173) = 1903
GCD(11, 173) = ( 11 x 173 ) / 1903
= 11 / 173
= 11
Step3:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
So, Greatest Common Divisor of 693, 781, 173, 406 is 1
