Given numbers are 420, 436, 853, 349

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

Apply this formula for all numbers.

Step1:

LCM(420, 436) = 45780

GCD(420, 436) = ( 420 x 436 ) / 45780

= 420 / 436

= 420

Step2:

LCM(4, 853) = 3412

GCD(4, 853) = ( 4 x 853 ) / 3412

= 4 / 853

= 4

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 420, 436, 853, 349 is 1
