The list of prime factors of all numbers are

Prime factors of 151 are 151

Prime factors of 787 are 787

Prime factors of 815 are 5 x 163

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 151, 787, 815, 142

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

Apply this formula for all numbers.

Step1:

LCM(151, 787) = 118837

GCD(151, 787) = ( 151 x 787 ) / 118837

= 151 / 787

= 151

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 142) = 142

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

= 1 / 142

= 1

So, Greatest Common Divisor of 151, 787, 815, 142 is 1
