Given numbers are 439, 454, 420, 419
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(439, 454) = 199306
GCD(439, 454) = ( 439 x 454 ) / 199306
= 439 / 454
= 439
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 439, 454, 420, 419 is 1
