Given numbers are 770, 393, 389, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 393) = 302610
GCD(770, 393) = ( 770 x 393 ) / 302610
= 770 / 393
= 770
Step2:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
Step3:
LCM(1, 745) = 745
GCD(1, 745) = ( 1 x 745 ) / 745
= 1 / 745
= 1
So, Greatest Common Divisor of 770, 393, 389, 745 is 1
