Given numbers are 455, 218, 754, 428

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

Apply this formula for all numbers.

Step1:

LCM(455, 218) = 99190

GCD(455, 218) = ( 455 x 218 ) / 99190

= 455 / 218

= 455

Step2:

LCM(1, 754) = 754

GCD(1, 754) = ( 1 x 754 ) / 754

= 1 / 754

= 1

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 455, 218, 754, 428 is 1
