Given numbers are 402, 274, 133, 491

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

Apply this formula for all numbers.

Step1:

LCM(402, 274) = 55074

GCD(402, 274) = ( 402 x 274 ) / 55074

= 402 / 274

= 402

Step2:

LCM(2, 133) = 266

GCD(2, 133) = ( 2 x 133 ) / 266

= 2 / 133

= 2

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 402, 274, 133, 491 is 1
