Given numbers are 154, 705, 172, 102

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 705 are 3 x 5 x 47

Prime factors of 172 are 2 x 2 x 43

Prime factors of 102 are 2 x 3 x 17

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

Given numbers are 154, 705, 172, 102

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

Apply this formula for all numbers.

Step1:

LCM(154, 705) = 108570

GCD(154, 705) = ( 154 x 705 ) / 108570

= 154 / 705

= 154

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 154, 705, 172, 102 is 1
