Given numbers are 623, 450, 409, 147

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 409 are 409

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 623, 450, 409, 147

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

Apply this formula for all numbers.

Step1:

LCM(623, 450) = 280350

GCD(623, 450) = ( 623 x 450 ) / 280350

= 623 / 450

= 623

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 623, 450, 409, 147 is 1
