Given numbers are 455, 417, 766, 769

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

Apply this formula for all numbers.

Step1:

LCM(455, 417) = 189735

GCD(455, 417) = ( 455 x 417 ) / 189735

= 455 / 417

= 455

Step2:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 455, 417, 766, 769 is 1
