Given numbers are 705, 991, 688, 445

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

Apply this formula for all numbers.

Step1:

LCM(705, 991) = 698655

GCD(705, 991) = ( 705 x 991 ) / 698655

= 705 / 991

= 705

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 705, 991, 688, 445 is 1
