Given numbers are 428, 989, 295, 637

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

Apply this formula for all numbers.

Step1:

LCM(428, 989) = 423292

GCD(428, 989) = ( 428 x 989 ) / 423292

= 428 / 989

= 428

Step2:

LCM(1, 295) = 295

GCD(1, 295) = ( 1 x 295 ) / 295

= 1 / 295

= 1

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 428, 989, 295, 637 is 1
