Given numbers are 745, 489, 257, 732
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(745, 489) = 364305
GCD(745, 489) = ( 745 x 489 ) / 364305
= 745 / 489
= 745
Step2:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
Step3:
LCM(1, 732) = 732
GCD(1, 732) = ( 1 x 732 ) / 732
= 1 / 732
= 1
So, Greatest Common Divisor of 745, 489, 257, 732 is 1
