Given numbers are 670, 774, 643, 825

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 643 are 643

Prime factors of 825 are 3 x 5 x 5 x 11

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

Given numbers are 670, 774, 643, 825

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

Apply this formula for all numbers.

Step1:

LCM(670, 774) = 259290

GCD(670, 774) = ( 670 x 774 ) / 259290

= 670 / 774

= 670

Step2:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

Step3:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

So, Greatest Common Divisor of 670, 774, 643, 825 is 1
