Given numbers are 816, 656, 447, 687

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

Apply this formula for all numbers.

Step1:

LCM(816, 656) = 33456

GCD(816, 656) = ( 816 x 656 ) / 33456

= 816 / 656

= 816

Step2:

LCM(16, 447) = 7152

GCD(16, 447) = ( 16 x 447 ) / 7152

= 16 / 447

= 16

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 816, 656, 447, 687 is 1
