Given numbers are 255, 489, 802, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 489) = 41565
GCD(255, 489) = ( 255 x 489 ) / 41565
= 255 / 489
= 255
Step2:
LCM(3, 802) = 2406
GCD(3, 802) = ( 3 x 802 ) / 2406
= 3 / 802
= 3
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 255, 489, 802, 307 is 1
