Given numbers are 902, 155, 345, 142

The list of prime factors of all numbers are

Prime factors of 902 are 2 x 11 x 41

Prime factors of 155 are 5 x 31

Prime factors of 345 are 3 x 5 x 23

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 902, 155, 345, 142

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

Apply this formula for all numbers.

Step1:

LCM(902, 155) = 139810

GCD(902, 155) = ( 902 x 155 ) / 139810

= 902 / 155

= 902

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 142) = 142

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

= 1 / 142

= 1

So, Greatest Common Divisor of 902, 155, 345, 142 is 1
