Given numbers are 628, 408, 745, 919

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

Apply this formula for all numbers.

Step1:

LCM(628, 408) = 64056

GCD(628, 408) = ( 628 x 408 ) / 64056

= 628 / 408

= 628

Step2:

LCM(4, 745) = 2980

GCD(4, 745) = ( 4 x 745 ) / 2980

= 4 / 745

= 4

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 628, 408, 745, 919 is 1
