Given numbers are 490, 325, 157, 990

The list of prime factors of all numbers are

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

Prime factors of 325 are 5 x 5 x 13

Prime factors of 157 are 157

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 490, 325, 157, 990

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

Apply this formula for all numbers.

Step1:

LCM(490, 325) = 31850

GCD(490, 325) = ( 490 x 325 ) / 31850

= 490 / 325

= 490

Step2:

LCM(5, 157) = 785

GCD(5, 157) = ( 5 x 157 ) / 785

= 5 / 157

= 5

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 490, 325, 157, 990 is 1
