Given numbers are 330, 308, 495, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(330, 308) = 4620
GCD(330, 308) = ( 330 x 308 ) / 4620
= 330 / 308
= 330
Step2:
LCM(22, 495) = 990
GCD(22, 495) = ( 22 x 495 ) / 990
= 22 / 495
= 22
Step3:
LCM(11, 257) = 2827
GCD(11, 257) = ( 11 x 257 ) / 2827
= 11 / 257
= 11
So, Greatest Common Divisor of 330, 308, 495, 257 is 1
