Given numbers are 620, 555, 291, 690

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 555 are 3 x 5 x 37

Prime factors of 291 are 3 x 97

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

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

Given numbers are 620, 555, 291, 690

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

Apply this formula for all numbers.

Step1:

LCM(620, 555) = 68820

GCD(620, 555) = ( 620 x 555 ) / 68820

= 620 / 555

= 620

Step2:

LCM(5, 291) = 1455

GCD(5, 291) = ( 5 x 291 ) / 1455

= 5 / 291

= 5

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 620, 555, 291, 690 is 1
