Given numbers are 701, 561, 820

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

Apply this formula for all numbers.

Step1:

LCM(701, 561) = 393261

GCD(701, 561) = ( 701 x 561 ) / 393261

= 701 / 561

= 701

Step2:

LCM(1, 820) = 820

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

= 1 / 820

= 1

So, Greatest Common Divisor of 701, 561, 820 is 1
