Given numbers are 281, 445, 644, 607

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, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

= 1 / 607

= 1

So, Greatest Common Divisor of 281, 445, 644, 607 is 1
