Given numbers are 981, 840, 396, 542

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 542 are 2 x 271

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 981, 840, 396, 542

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

Apply this formula for all numbers.

Step1:

LCM(981, 840) = 274680

GCD(981, 840) = ( 981 x 840 ) / 274680

= 981 / 840

= 981

Step2:

LCM(3, 396) = 396

GCD(3, 396) = ( 3 x 396 ) / 396

= 3 / 396

= 3

Step3:

LCM(3, 542) = 1626

GCD(3, 542) = ( 3 x 542 ) / 1626

= 3 / 542

= 3

So, Greatest Common Divisor of 981, 840, 396, 542 is 1
