Given numbers are 662, 636, 644, 815

The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 815 are 5 x 163

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

Given numbers are 662, 636, 644, 815

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

Apply this formula for all numbers.

Step1:

LCM(662, 636) = 210516

GCD(662, 636) = ( 662 x 636 ) / 210516

= 662 / 636

= 662

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 662, 636, 644, 815 is 1
