Given numbers are 646, 257, 130, 176

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

Apply this formula for all numbers.

Step1:

LCM(646, 257) = 166022

GCD(646, 257) = ( 646 x 257 ) / 166022

= 646 / 257

= 646

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 176) = 176

GCD(1, 176) = ( 1 x 176 ) / 176

= 1 / 176

= 1

So, Greatest Common Divisor of 646, 257, 130, 176 is 1
