Given numbers are 806, 745, 869, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(806, 745) = 600470
GCD(806, 745) = ( 806 x 745 ) / 600470
= 806 / 745
= 806
Step2:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 806, 745, 869, 921 is 1
