GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 989) = 433182
GCD(438, 989) = ( 438 x 989 ) / 433182
= 438 / 989
= 438
Step2:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
Step3:
LCM(1, 469) = 469
GCD(1, 469) = ( 1 x 469 ) / 469
= 1 / 469
= 1
So, Greatest Common Divisor of 438, 989, 897, 469 is 1
