Given numbers are 645, 532, 242, 142

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 532 are 2 x 2 x 7 x 19

Prime factors of 242 are 2 x 11 x 11

Prime factors of 142 are 2 x 71

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

Given numbers are 645, 532, 242, 142

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

Apply this formula for all numbers.

Step1:

LCM(645, 532) = 343140

GCD(645, 532) = ( 645 x 532 ) / 343140

= 645 / 532

= 645

Step2:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 645, 532, 242, 142 is 1
