Given numbers are 646, 109, 772

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

Apply this formula for all numbers.

Step1:

LCM(646, 109) = 70414

GCD(646, 109) = ( 646 x 109 ) / 70414

= 646 / 109

= 646

Step2:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 646, 109, 772 is 1
