Given numbers are 380, 395, 815, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 395) = 30020
GCD(380, 395) = ( 380 x 395 ) / 30020
= 380 / 395
= 380
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 657) = 3285
GCD(5, 657) = ( 5 x 657 ) / 3285
= 5 / 657
= 5
So, Greatest Common Divisor of 380, 395, 815, 657 is 1
