Given numbers are 789, 390, 470, 879
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 390) = 102570
GCD(789, 390) = ( 789 x 390 ) / 102570
= 789 / 390
= 789
Step2:
LCM(3, 470) = 1410
GCD(3, 470) = ( 3 x 470 ) / 1410
= 3 / 470
= 3
Step3:
LCM(1, 879) = 879
GCD(1, 879) = ( 1 x 879 ) / 879
= 1 / 879
= 1
So, Greatest Common Divisor of 789, 390, 470, 879 is 1
