Given numbers are 787, 177, 620

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

Apply this formula for all numbers.

Step1:

LCM(787, 177) = 139299

GCD(787, 177) = ( 787 x 177 ) / 139299

= 787 / 177

= 787

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 787, 177, 620 is 1
