GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 897) = 700557
GCD(781, 897) = ( 781 x 897 ) / 700557
= 781 / 897
= 781
Step2:
LCM(1, 951) = 951
GCD(1, 951) = ( 1 x 951 ) / 951
= 1 / 951
= 1
Step3:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
So, Greatest Common Divisor of 781, 897, 951, 765 is 1
