Given numbers are 448, 721, 553, 425

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

Apply this formula for all numbers.

Step1:

LCM(448, 721) = 46144

GCD(448, 721) = ( 448 x 721 ) / 46144

= 448 / 721

= 448

Step2:

LCM(7, 553) = 553

GCD(7, 553) = ( 7 x 553 ) / 553

= 7 / 553

= 7

Step3:

LCM(7, 425) = 2975

GCD(7, 425) = ( 7 x 425 ) / 2975

= 7 / 425

= 7

So, Greatest Common Divisor of 448, 721, 553, 425 is 1
