Given numbers are 307, 248, 772, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(307, 248) = 76136
GCD(307, 248) = ( 307 x 248 ) / 76136
= 307 / 248
= 307
Step2:
LCM(1, 772) = 772
GCD(1, 772) = ( 1 x 772 ) / 772
= 1 / 772
= 1
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 307, 248, 772, 409 is 1
