Given numbers are 780, 789, 795, 951
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 789) = 205140
GCD(780, 789) = ( 780 x 789 ) / 205140
= 780 / 789
= 780
Step2:
LCM(3, 795) = 795
GCD(3, 795) = ( 3 x 795 ) / 795
= 3 / 795
= 3
Step3:
LCM(3, 951) = 951
GCD(3, 951) = ( 3 x 951 ) / 951
= 3 / 951
= 3
So, Greatest Common Divisor of 780, 789, 795, 951 is 3
