Given numbers are 816, 288, 139, 820

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

Apply this formula for all numbers.

Step1:

LCM(816, 288) = 4896

GCD(816, 288) = ( 816 x 288 ) / 4896

= 816 / 288

= 816

Step2:

LCM(48, 139) = 6672

GCD(48, 139) = ( 48 x 139 ) / 6672

= 48 / 139

= 48

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 816, 288, 139, 820 is 1
