Given numbers are 745, 906, 820, 450

The list of prime factors of all numbers are

Prime factors of 745 are 5 x 149

Prime factors of 906 are 2 x 3 x 151

Prime factors of 820 are 2 x 2 x 5 x 41

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

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

Given numbers are 745, 906, 820, 450

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

Apply this formula for all numbers.

Step1:

LCM(745, 906) = 674970

GCD(745, 906) = ( 745 x 906 ) / 674970

= 745 / 906

= 745

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 745, 906, 820, 450 is 1
