Given numbers are 290, 781, 222, 142

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 781 are 11 x 71

Prime factors of 222 are 2 x 3 x 37

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 290, 781, 222, 142

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

Apply this formula for all numbers.

Step1:

LCM(290, 781) = 226490

GCD(290, 781) = ( 290 x 781 ) / 226490

= 290 / 781

= 290

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 142) = 142

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

= 1 / 142

= 1

So, Greatest Common Divisor of 290, 781, 222, 142 is 1
