Given numbers are 658, 170, 625, 551

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 170 are 2 x 5 x 17

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 551 are 19 x 29

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

Given numbers are 658, 170, 625, 551

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

Apply this formula for all numbers.

Step1:

LCM(658, 170) = 55930

GCD(658, 170) = ( 658 x 170 ) / 55930

= 658 / 170

= 658

Step2:

LCM(2, 625) = 1250

GCD(2, 625) = ( 2 x 625 ) / 1250

= 2 / 625

= 2

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 658, 170, 625, 551 is 1
