Given numbers are 243, 308, 922, 780

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(243, 308) = 74844

GCD(243, 308) = ( 243 x 308 ) / 74844

= 243 / 308

= 243

Step2:

LCM(1, 922) = 922

GCD(1, 922) = ( 1 x 922 ) / 922

= 1 / 922

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 243, 308, 922, 780 is 1
