Given numbers are 785, 965, 21

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

Apply this formula for all numbers.

Step1:

LCM(785, 965) = 151505

GCD(785, 965) = ( 785 x 965 ) / 151505

= 785 / 965

= 785

Step2:

LCM(5, 21) = 105

GCD(5, 21) = ( 5 x 21 ) / 105

= 5 / 21

= 5

So, Greatest Common Divisor of 785, 965, 21 is 1
