Given numbers are 305, 485, 879, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 485) = 29585
GCD(305, 485) = ( 305 x 485 ) / 29585
= 305 / 485
= 305
Step2:
LCM(5, 879) = 4395
GCD(5, 879) = ( 5 x 879 ) / 4395
= 5 / 879
= 5
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 305, 485, 879, 438 is 1
