Given numbers are 649, 782, 340, 351

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 782 are 2 x 17 x 23

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 351 are 3 x 3 x 3 x 13

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

Given numbers are 649, 782, 340, 351

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

Apply this formula for all numbers.

Step1:

LCM(649, 782) = 507518

GCD(649, 782) = ( 649 x 782 ) / 507518

= 649 / 782

= 649

Step2:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

Step3:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

So, Greatest Common Divisor of 649, 782, 340, 351 is 1
