Given numbers are 620, 649, 172

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

Apply this formula for all numbers.

Step1:

LCM(620, 649) = 402380

GCD(620, 649) = ( 620 x 649 ) / 402380

= 620 / 649

= 620

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 620, 649, 172 is 1
