Given numbers are 282, 620, 257, 665

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

Apply this formula for all numbers.

Step1:

LCM(282, 620) = 87420

GCD(282, 620) = ( 282 x 620 ) / 87420

= 282 / 620

= 282

Step2:

LCM(2, 257) = 514

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

= 2 / 257

= 2

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 282, 620, 257, 665 is 1
