Given numbers are 628, 639, 920

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

Apply this formula for all numbers.

Step1:

LCM(628, 639) = 401292

GCD(628, 639) = ( 628 x 639 ) / 401292

= 628 / 639

= 628

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 628, 639, 920 is 1
