Given numbers are 840, 397, 824, 248

The list of prime factors of all numbers are

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

Prime factors of 397 are 397

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 248 are 2 x 2 x 2 x 31

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

Given numbers are 840, 397, 824, 248

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

Apply this formula for all numbers.

Step1:

LCM(840, 397) = 333480

GCD(840, 397) = ( 840 x 397 ) / 333480

= 840 / 397

= 840

Step2:

LCM(1, 824) = 824

GCD(1, 824) = ( 1 x 824 ) / 824

= 1 / 824

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 840, 397, 824, 248 is 1
