Given numbers are 660, 242, 836, 855

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 242 are 2 x 11 x 11

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 660, 242, 836, 855

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

Apply this formula for all numbers.

Step1:

LCM(660, 242) = 7260

GCD(660, 242) = ( 660 x 242 ) / 7260

= 660 / 242

= 660

Step2:

LCM(22, 836) = 836

GCD(22, 836) = ( 22 x 836 ) / 836

= 22 / 836

= 22

Step3:

LCM(22, 855) = 18810

GCD(22, 855) = ( 22 x 855 ) / 18810

= 22 / 855

= 22

So, Greatest Common Divisor of 660, 242, 836, 855 is 1
