Given numbers are 428, 127, 997, 153

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

Apply this formula for all numbers.

Step1:

LCM(428, 127) = 54356

GCD(428, 127) = ( 428 x 127 ) / 54356

= 428 / 127

= 428

Step2:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

Step3:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

So, Greatest Common Divisor of 428, 127, 997, 153 is 1
