Given numbers are 653, 456, 840, 697

The list of prime factors of all numbers are

Prime factors of 653 are 653

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 697 are 17 x 41

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

Given numbers are 653, 456, 840, 697

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

Apply this formula for all numbers.

Step1:

LCM(653, 456) = 297768

GCD(653, 456) = ( 653 x 456 ) / 297768

= 653 / 456

= 653

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 697) = 697

GCD(1, 697) = ( 1 x 697 ) / 697

= 1 / 697

= 1

So, Greatest Common Divisor of 653, 456, 840, 697 is 1
