Given numbers are 351, 981, 938, 641

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

Apply this formula for all numbers.

Step1:

LCM(351, 981) = 38259

GCD(351, 981) = ( 351 x 981 ) / 38259

= 351 / 981

= 351

Step2:

LCM(9, 938) = 8442

GCD(9, 938) = ( 9 x 938 ) / 8442

= 9 / 938

= 9

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 351, 981, 938, 641 is 1
