Given numbers are 690, 791, 455, 652

The list of prime factors of all numbers are

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

Prime factors of 791 are 7 x 113

Prime factors of 455 are 5 x 7 x 13

Prime factors of 652 are 2 x 2 x 163

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

Given numbers are 690, 791, 455, 652

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

Apply this formula for all numbers.

Step1:

LCM(690, 791) = 545790

GCD(690, 791) = ( 690 x 791 ) / 545790

= 690 / 791

= 690

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

So, Greatest Common Divisor of 690, 791, 455, 652 is 1
