Given numbers are 770, 209, 985, 315

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 209 are 11 x 19

Prime factors of 985 are 5 x 197

Prime factors of 315 are 3 x 3 x 5 x 7

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

Given numbers are 770, 209, 985, 315

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

Apply this formula for all numbers.

Step1:

LCM(770, 209) = 14630

GCD(770, 209) = ( 770 x 209 ) / 14630

= 770 / 209

= 770

Step2:

LCM(11, 985) = 10835

GCD(11, 985) = ( 11 x 985 ) / 10835

= 11 / 985

= 11

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 770, 209, 985, 315 is 1
