GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(307, 489) = 150123
GCD(307, 489) = ( 307 x 489 ) / 150123
= 307 / 489
= 307
Step2:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 307, 489, 943, 455 is 1
