Given numbers are 426, 207, 202, 421

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

Apply this formula for all numbers.

Step1:

LCM(426, 207) = 29394

GCD(426, 207) = ( 426 x 207 ) / 29394

= 426 / 207

= 426

Step2:

LCM(3, 202) = 606

GCD(3, 202) = ( 3 x 202 ) / 606

= 3 / 202

= 3

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 426, 207, 202, 421 is 1
