Given numbers are 140, 663, 252, 778

The list of prime factors of all numbers are

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

Prime factors of 663 are 3 x 13 x 17

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 778 are 2 x 389

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

Given numbers are 140, 663, 252, 778

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

Apply this formula for all numbers.

Step1:

LCM(140, 663) = 92820

GCD(140, 663) = ( 140 x 663 ) / 92820

= 140 / 663

= 140

Step2:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 140, 663, 252, 778 is 1
