Given numbers are 281, 445, 647, 580

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

Apply this formula for all numbers.

Step1:

LCM(281, 445) = 125045

GCD(281, 445) = ( 281 x 445 ) / 125045

= 281 / 445

= 281

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 281, 445, 647, 580 is 1
