Given numbers are 390, 878, 176, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 878) = 171210
GCD(390, 878) = ( 390 x 878 ) / 171210
= 390 / 878
= 390
Step2:
LCM(2, 176) = 176
GCD(2, 176) = ( 2 x 176 ) / 176
= 2 / 176
= 2
Step3:
LCM(2, 305) = 610
GCD(2, 305) = ( 2 x 305 ) / 610
= 2 / 305
= 2
So, Greatest Common Divisor of 390, 878, 176, 305 is 1
