GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 969) = 414732
GCD(428, 969) = ( 428 x 969 ) / 414732
= 428 / 969
= 428
Step2:
LCM(1, 887) = 887
GCD(1, 887) = ( 1 x 887 ) / 887
= 1 / 887
= 1
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 428, 969, 887, 449 is 1
