GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 697) = 271830
GCD(390, 697) = ( 390 x 697 ) / 271830
= 390 / 697
= 390
Step2:
LCM(1, 719) = 719
GCD(1, 719) = ( 1 x 719 ) / 719
= 1 / 719
= 1
Step3:
LCM(1, 969) = 969
GCD(1, 969) = ( 1 x 969 ) / 969
= 1 / 969
= 1
So, Greatest Common Divisor of 390, 697, 719, 969 is 1
