Given numbers are 920, 836, 885, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 836) = 192280
GCD(920, 836) = ( 920 x 836 ) / 192280
= 920 / 836
= 920
Step2:
LCM(4, 885) = 3540
GCD(4, 885) = ( 4 x 885 ) / 3540
= 4 / 885
= 4
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 920, 836, 885, 390 is 1
