Given numbers are 693, 770, 140, 643

The list of prime factors of all numbers are

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 643 are 643

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

Given numbers are 693, 770, 140, 643

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

Apply this formula for all numbers.

Step1:

LCM(693, 770) = 6930

GCD(693, 770) = ( 693 x 770 ) / 6930

= 693 / 770

= 693

Step2:

LCM(77, 140) = 1540

GCD(77, 140) = ( 77 x 140 ) / 1540

= 77 / 140

= 77

Step3:

LCM(7, 643) = 4501

GCD(7, 643) = ( 7 x 643 ) / 4501

= 7 / 643

= 7

So, Greatest Common Divisor of 693, 770, 140, 643 is 1
