Given numbers are 142, 499, 840, 785

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 499 are 499

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 785 are 5 x 157

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

Given numbers are 142, 499, 840, 785

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

Apply this formula for all numbers.

Step1:

LCM(142, 499) = 70858

GCD(142, 499) = ( 142 x 499 ) / 70858

= 142 / 499

= 142

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 142, 499, 840, 785 is 1
