Given numbers are 705, 807, 787, 865

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

Apply this formula for all numbers.

Step1:

LCM(705, 807) = 189645

GCD(705, 807) = ( 705 x 807 ) / 189645

= 705 / 807

= 705

Step2:

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

= 3 / 787

= 3

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 705, 807, 787, 865 is 1
