Given numbers are 263, 653, 863, 455

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

Apply this formula for all numbers.

Step1:

LCM(263, 653) = 171739

GCD(263, 653) = ( 263 x 653 ) / 171739

= 263 / 653

= 263

Step2:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

Step3:

LCM(1, 455) = 455

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

= 1 / 455

= 1

So, Greatest Common Divisor of 263, 653, 863, 455 is 1
