Given numbers are 465, 447, 455, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(465, 447) = 69285
GCD(465, 447) = ( 465 x 447 ) / 69285
= 465 / 447
= 465
Step2:
LCM(3, 455) = 1365
GCD(3, 455) = ( 3 x 455 ) / 1365
= 3 / 455
= 3
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 465, 447, 455, 257 is 1
