GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(724, 419) = 303356
GCD(724, 419) = ( 724 x 419 ) / 303356
= 724 / 419
= 724
Step2:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 724, 419, 428, 809 is 1
