Given numbers are 389, 764, 619, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 764) = 297196
GCD(389, 764) = ( 389 x 764 ) / 297196
= 389 / 764
= 389
Step2:
LCM(1, 619) = 619
GCD(1, 619) = ( 1 x 619 ) / 619
= 1 / 619
= 1
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 389, 764, 619, 790 is 1
