Given numbers are 455, 949, 639, 583

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(455, 949) = 33215

GCD(455, 949) = ( 455 x 949 ) / 33215

= 455 / 949

= 455

Step2:

LCM(13, 639) = 8307

GCD(13, 639) = ( 13 x 639 ) / 8307

= 13 / 639

= 13

Step3:

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

= 1 / 583

= 1

So, Greatest Common Divisor of 455, 949, 639, 583 is 1
