Given numbers are 655, 194, 180, 715

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 194 are 2 x 97

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 715 are 5 x 11 x 13

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

Given numbers are 655, 194, 180, 715

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

Apply this formula for all numbers.

Step1:

LCM(655, 194) = 127070

GCD(655, 194) = ( 655 x 194 ) / 127070

= 655 / 194

= 655

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 655, 194, 180, 715 is 1
