Given numbers are 637, 611, 890, 455

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

Apply this formula for all numbers.

Step1:

LCM(637, 611) = 29939

GCD(637, 611) = ( 637 x 611 ) / 29939

= 637 / 611

= 637

Step2:

LCM(13, 890) = 11570

GCD(13, 890) = ( 13 x 890 ) / 11570

= 13 / 890

= 13

Step3:

LCM(1, 455) = 455

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

= 1 / 455

= 1

So, Greatest Common Divisor of 637, 611, 890, 455 is 1
