Given numbers are 398, 256, 387, 365
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 256) = 50944
GCD(398, 256) = ( 398 x 256 ) / 50944
= 398 / 256
= 398
Step2:
LCM(2, 387) = 774
GCD(2, 387) = ( 2 x 387 ) / 774
= 2 / 387
= 2
Step3:
LCM(1, 365) = 365
GCD(1, 365) = ( 1 x 365 ) / 365
= 1 / 365
= 1
So, Greatest Common Divisor of 398, 256, 387, 365 is 1
