Given numbers are 917, 257, 644, 627

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

Apply this formula for all numbers.

Step1:

LCM(917, 257) = 235669

GCD(917, 257) = ( 917 x 257 ) / 235669

= 917 / 257

= 917

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 627) = 627

GCD(1, 627) = ( 1 x 627 ) / 627

= 1 / 627

= 1

So, Greatest Common Divisor of 917, 257, 644, 627 is 1
