Given numbers are 817, 867, 305, 387
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(817, 867) = 708339
GCD(817, 867) = ( 817 x 867 ) / 708339
= 817 / 867
= 817
Step2:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 817, 867, 305, 387 is 1
