Given numbers are 253, 126, 943, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 126) = 31878
GCD(253, 126) = ( 253 x 126 ) / 31878
= 253 / 126
= 253
Step2:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 253, 126, 943, 489 is 1
