Given numbers are 340, 440, 87, 142

The list of prime factors of all numbers are

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 87 are 3 x 29

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 340, 440, 87, 142

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

Apply this formula for all numbers.

Step1:

LCM(340, 440) = 7480

GCD(340, 440) = ( 340 x 440 ) / 7480

= 340 / 440

= 340

Step2:

LCM(20, 87) = 1740

GCD(20, 87) = ( 20 x 87 ) / 1740

= 20 / 87

= 20

Step3:

LCM(1, 142) = 142

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

= 1 / 142

= 1

So, Greatest Common Divisor of 340, 440, 87, 142 is 1
