Given numbers are 455, 835, 283, 220

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

Apply this formula for all numbers.

Step1:

LCM(455, 835) = 75985

GCD(455, 835) = ( 455 x 835 ) / 75985

= 455 / 835

= 455

Step2:

LCM(5, 283) = 1415

GCD(5, 283) = ( 5 x 283 ) / 1415

= 5 / 283

= 5

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 455, 835, 283, 220 is 1
