Given numbers are 454, 155, 903, 220

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

Apply this formula for all numbers.

Step1:

LCM(454, 155) = 70370

GCD(454, 155) = ( 454 x 155 ) / 70370

= 454 / 155

= 454

Step2:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

Step3:

LCM(1, 220) = 220

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

= 1 / 220

= 1

So, Greatest Common Divisor of 454, 155, 903, 220 is 1
