Given numbers are 690, 177, 176, 648

The list of prime factors of all numbers are

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

Prime factors of 177 are 3 x 59

Prime factors of 176 are 2 x 2 x 2 x 2 x 11

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 690, 177, 176, 648

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

Apply this formula for all numbers.

Step1:

LCM(690, 177) = 40710

GCD(690, 177) = ( 690 x 177 ) / 40710

= 690 / 177

= 690

Step2:

LCM(3, 176) = 528

GCD(3, 176) = ( 3 x 176 ) / 528

= 3 / 176

= 3

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 690, 177, 176, 648 is 1
