Given numbers are 394, 644, 202, 281

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

Apply this formula for all numbers.

Step1:

LCM(394, 644) = 126868

GCD(394, 644) = ( 394 x 644 ) / 126868

= 394 / 644

= 394

Step2:

LCM(2, 202) = 202

GCD(2, 202) = ( 2 x 202 ) / 202

= 2 / 202

= 2

Step3:

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

= 2 / 281

= 2

So, Greatest Common Divisor of 394, 644, 202, 281 is 1
