Given numbers are 545, 243, 285, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 243) = 132435
GCD(545, 243) = ( 545 x 243 ) / 132435
= 545 / 243
= 545
Step2:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 545, 243, 285, 307 is 1
