Given numbers are 781, 426, 477, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 426) = 4686
GCD(781, 426) = ( 781 x 426 ) / 4686
= 781 / 426
= 781
Step2:
LCM(71, 477) = 33867
GCD(71, 477) = ( 71 x 477 ) / 33867
= 71 / 477
= 71
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 781, 426, 477, 166 is 1
