Given numbers are 390, 359, 512, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 359) = 140010
GCD(390, 359) = ( 390 x 359 ) / 140010
= 390 / 359
= 390
Step2:
LCM(1, 512) = 512
GCD(1, 512) = ( 1 x 512 ) / 512
= 1 / 512
= 1
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 390, 359, 512, 836 is 1
