Given numbers are 628, 719, 641, 905

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

Apply this formula for all numbers.

Step1:

LCM(628, 719) = 451532

GCD(628, 719) = ( 628 x 719 ) / 451532

= 628 / 719

= 628

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 628, 719, 641, 905 is 1
