Given numbers are 945, 196, 340, 785

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 196 are 2 x 2 x 7 x 7

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

Prime factors of 785 are 5 x 157

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

Given numbers are 945, 196, 340, 785

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

Apply this formula for all numbers.

Step1:

LCM(945, 196) = 26460

GCD(945, 196) = ( 945 x 196 ) / 26460

= 945 / 196

= 945

Step2:

LCM(7, 340) = 2380

GCD(7, 340) = ( 7 x 340 ) / 2380

= 7 / 340

= 7

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 945, 196, 340, 785 is 1
