Given numbers are 252, 343, 129, 891

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

Apply this formula for all numbers.

Step1:

LCM(252, 343) = 12348

GCD(252, 343) = ( 252 x 343 ) / 12348

= 252 / 343

= 252

Step2:

LCM(7, 129) = 903

GCD(7, 129) = ( 7 x 129 ) / 903

= 7 / 129

= 7

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 252, 343, 129, 891 is 1
