Given numbers are 712, 716, 809, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(712, 716) = 127448
GCD(712, 716) = ( 712 x 716 ) / 127448
= 712 / 716
= 712
Step2:
LCM(4, 809) = 3236
GCD(4, 809) = ( 4 x 809 ) / 3236
= 4 / 809
= 4
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 712, 716, 809, 305 is 1
