Given numbers are 490, 755, 291, 309

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 755 are 5 x 151

Prime factors of 291 are 3 x 97

Prime factors of 309 are 3 x 103

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

Given numbers are 490, 755, 291, 309

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

Apply this formula for all numbers.

Step1:

LCM(490, 755) = 73990

GCD(490, 755) = ( 490 x 755 ) / 73990

= 490 / 755

= 490

Step2:

LCM(5, 291) = 1455

GCD(5, 291) = ( 5 x 291 ) / 1455

= 5 / 291

= 5

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 490, 755, 291, 309 is 1
