Given numbers are 489, 287, 925, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 287) = 140343
GCD(489, 287) = ( 489 x 287 ) / 140343
= 489 / 287
= 489
Step2:
LCM(1, 925) = 925
GCD(1, 925) = ( 1 x 925 ) / 925
= 1 / 925
= 1
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 489, 287, 925, 637 is 1
