Given numbers are 278, 550, 417, 628

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

Apply this formula for all numbers.

Step1:

LCM(278, 550) = 76450

GCD(278, 550) = ( 278 x 550 ) / 76450

= 278 / 550

= 278

Step2:

LCM(2, 417) = 834

GCD(2, 417) = ( 2 x 417 ) / 834

= 2 / 417

= 2

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 278, 550, 417, 628 is 1
