Given numbers are 548, 428, 45, 631

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

Apply this formula for all numbers.

Step1:

LCM(548, 428) = 58636

GCD(548, 428) = ( 548 x 428 ) / 58636

= 548 / 428

= 548

Step2:

LCM(4, 45) = 180

GCD(4, 45) = ( 4 x 45 ) / 180

= 4 / 45

= 4

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 548, 428, 45, 631 is 1
