Given numbers are 202, 644, 636, 155

The list of prime factors of all numbers are

Prime factors of 202 are 2 x 101

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

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

Prime factors of 155 are 5 x 31

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

Given numbers are 202, 644, 636, 155

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

Apply this formula for all numbers.

Step1:

LCM(202, 644) = 65044

GCD(202, 644) = ( 202 x 644 ) / 65044

= 202 / 644

= 202

Step2:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

Step3:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

So, Greatest Common Divisor of 202, 644, 636, 155 is 1
