Given numbers are 421, 418, 802, 207

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

Apply this formula for all numbers.

Step1:

LCM(421, 418) = 175978

GCD(421, 418) = ( 421 x 418 ) / 175978

= 421 / 418

= 421

Step2:

LCM(1, 802) = 802

GCD(1, 802) = ( 1 x 802 ) / 802

= 1 / 802

= 1

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 421, 418, 802, 207 is 1
