Given numbers are 705, 643, 40, 997

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

Apply this formula for all numbers.

Step1:

LCM(705, 643) = 453315

GCD(705, 643) = ( 705 x 643 ) / 453315

= 705 / 643

= 705

Step2:

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

= 1 / 40

= 1

Step3:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

So, Greatest Common Divisor of 705, 643, 40, 997 is 1
