Given numbers are 140, 890, 693, 680

The list of prime factors of all numbers are

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

Prime factors of 890 are 2 x 5 x 89

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

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 140, 890, 693, 680

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

Apply this formula for all numbers.

Step1:

LCM(140, 890) = 12460

GCD(140, 890) = ( 140 x 890 ) / 12460

= 140 / 890

= 140

Step2:

LCM(10, 693) = 6930

GCD(10, 693) = ( 10 x 693 ) / 6930

= 10 / 693

= 10

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 140, 890, 693, 680 is 1
