GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(712, 378) = 134568
GCD(712, 378) = ( 712 x 378 ) / 134568
= 712 / 378
= 712
Step2:
LCM(2, 389) = 778
GCD(2, 389) = ( 2 x 389 ) / 778
= 2 / 389
= 2
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 712, 378, 389, 815 is 1
