Given numbers are 655, 803, 686, 624

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 803 are 11 x 73

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 655, 803, 686, 624

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

Apply this formula for all numbers.

Step1:

LCM(655, 803) = 525965

GCD(655, 803) = ( 655 x 803 ) / 525965

= 655 / 803

= 655

Step2:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 655, 803, 686, 624 is 1
