Given numbers are 343, 755, 753, 840

The list of prime factors of all numbers are

Prime factors of 343 are 7 x 7 x 7

Prime factors of 755 are 5 x 151

Prime factors of 753 are 3 x 251

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

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

Given numbers are 343, 755, 753, 840

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

Apply this formula for all numbers.

Step1:

LCM(343, 755) = 258965

GCD(343, 755) = ( 343 x 755 ) / 258965

= 343 / 755

= 343

Step2:

LCM(1, 753) = 753

GCD(1, 753) = ( 1 x 753 ) / 753

= 1 / 753

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 343, 755, 753, 840 is 1
