Given numbers are 287, 256, 289, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 256) = 73472
GCD(287, 256) = ( 287 x 256 ) / 73472
= 287 / 256
= 287
Step2:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 287, 256, 289, 307 is 1
