Given numbers are 553, 631, 166, 455

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

Apply this formula for all numbers.

Step1:

LCM(553, 631) = 348943

GCD(553, 631) = ( 553 x 631 ) / 348943

= 553 / 631

= 553

Step2:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 553, 631, 166, 455 is 1
