Given numbers are 153, 648, 990, 451

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Prime factors of 451 are 11 x 41

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

Given numbers are 153, 648, 990, 451

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

Apply this formula for all numbers.

Step1:

LCM(153, 648) = 11016

GCD(153, 648) = ( 153 x 648 ) / 11016

= 153 / 648

= 153

Step2:

LCM(9, 990) = 990

GCD(9, 990) = ( 9 x 990 ) / 990

= 9 / 990

= 9

Step3:

LCM(9, 451) = 4059

GCD(9, 451) = ( 9 x 451 ) / 4059

= 9 / 451

= 9

So, Greatest Common Divisor of 153, 648, 990, 451 is 1
