Given numbers are 248, 580, 445, 688

The list of prime factors of all numbers are

Prime factors of 248 are 2 x 2 x 2 x 31

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 445 are 5 x 89

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 248, 580, 445, 688

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

Apply this formula for all numbers.

Step1:

LCM(248, 580) = 35960

GCD(248, 580) = ( 248 x 580 ) / 35960

= 248 / 580

= 248

Step2:

LCM(4, 445) = 1780

GCD(4, 445) = ( 4 x 445 ) / 1780

= 4 / 445

= 4

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 248, 580, 445, 688 is 1
