Given numbers are 137, 117, 820

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

Apply this formula for all numbers.

Step1:

LCM(137, 117) = 16029

GCD(137, 117) = ( 137 x 117 ) / 16029

= 137 / 117

= 137

Step2:

LCM(1, 820) = 820

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

= 1 / 820

= 1

So, Greatest Common Divisor of 137, 117, 820 is 1
