Given numbers are 645, 458, 650, 370

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 458 are 2 x 229

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 370 are 2 x 5 x 37

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

Given numbers are 645, 458, 650, 370

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

Apply this formula for all numbers.

Step1:

LCM(645, 458) = 295410

GCD(645, 458) = ( 645 x 458 ) / 295410

= 645 / 458

= 645

Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

So, Greatest Common Divisor of 645, 458, 650, 370 is 1
