Given numbers are 816, 646, 83, 853

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

Apply this formula for all numbers.

Step1:

LCM(816, 646) = 15504

GCD(816, 646) = ( 816 x 646 ) / 15504

= 816 / 646

= 816

Step2:

LCM(34, 83) = 2822

GCD(34, 83) = ( 34 x 83 ) / 2822

= 34 / 83

= 34

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 816, 646, 83, 853 is 1
