Given numbers are 306, 780, 811, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(306, 780) = 39780
GCD(306, 780) = ( 306 x 780 ) / 39780
= 306 / 780
= 306
Step2:
LCM(6, 811) = 4866
GCD(6, 811) = ( 6 x 811 ) / 4866
= 6 / 811
= 6
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 306, 780, 811, 385 is 1
