Given numbers are 434, 142, 916, 257

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

Apply this formula for all numbers.

Step1:

LCM(434, 142) = 30814

GCD(434, 142) = ( 434 x 142 ) / 30814

= 434 / 142

= 434

Step2:

LCM(2, 916) = 916

GCD(2, 916) = ( 2 x 916 ) / 916

= 2 / 916

= 2

Step3:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

So, Greatest Common Divisor of 434, 142, 916, 257 is 1
