Given numbers are 390, 789, 519, 695
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 789) = 102570
GCD(390, 789) = ( 390 x 789 ) / 102570
= 390 / 789
= 390
Step2:
LCM(3, 519) = 519
GCD(3, 519) = ( 3 x 519 ) / 519
= 3 / 519
= 3
Step3:
LCM(3, 695) = 2085
GCD(3, 695) = ( 3 x 695 ) / 2085
= 3 / 695
= 3
So, Greatest Common Divisor of 390, 789, 519, 695 is 1
