Given numbers are 488, 645, 475, 281

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

Apply this formula for all numbers.

Step1:

LCM(488, 645) = 314760

GCD(488, 645) = ( 488 x 645 ) / 314760

= 488 / 645

= 488

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 488, 645, 475, 281 is 1
