Given numbers are 690, 588, 77, 170

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 588 are 2 x 2 x 3 x 7 x 7

Prime factors of 77 are 7 x 11

Prime factors of 170 are 2 x 5 x 17

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

Given numbers are 690, 588, 77, 170

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

Apply this formula for all numbers.

Step1:

LCM(690, 588) = 67620

GCD(690, 588) = ( 690 x 588 ) / 67620

= 690 / 588

= 690

Step2:

LCM(6, 77) = 462

GCD(6, 77) = ( 6 x 77 ) / 462

= 6 / 77

= 6

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 690, 588, 77, 170 is 1
