Given numbers are 806, 260, 138, 477
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(806, 260) = 8060
GCD(806, 260) = ( 806 x 260 ) / 8060
= 806 / 260
= 806
Step2:
LCM(26, 138) = 1794
GCD(26, 138) = ( 26 x 138 ) / 1794
= 26 / 138
= 26
Step3:
LCM(2, 477) = 954
GCD(2, 477) = ( 2 x 477 ) / 954
= 2 / 477
= 2
So, Greatest Common Divisor of 806, 260, 138, 477 is 1
