Given numbers are 807, 409, 651, 208

The list of prime factors of all numbers are

Prime factors of 807 are 3 x 269

Prime factors of 409 are 409

Prime factors of 651 are 3 x 7 x 31

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

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

Given numbers are 807, 409, 651, 208

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

Apply this formula for all numbers.

Step1:

LCM(807, 409) = 330063

GCD(807, 409) = ( 807 x 409 ) / 330063

= 807 / 409

= 807

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 807, 409, 651, 208 is 1
