Given numbers are 195, 255, 308, 549
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(195, 255) = 3315
GCD(195, 255) = ( 195 x 255 ) / 3315
= 195 / 255
= 195
Step2:
LCM(15, 308) = 4620
GCD(15, 308) = ( 15 x 308 ) / 4620
= 15 / 308
= 15
Step3:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
So, Greatest Common Divisor of 195, 255, 308, 549 is 1
