Given numbers are 140, 504, 206, 561

The list of prime factors of all numbers are

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

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 206 are 2 x 103

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 140, 504, 206, 561

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

Apply this formula for all numbers.

Step1:

LCM(140, 504) = 2520

GCD(140, 504) = ( 140 x 504 ) / 2520

= 140 / 504

= 140

Step2:

LCM(28, 206) = 2884

GCD(28, 206) = ( 28 x 206 ) / 2884

= 28 / 206

= 28

Step3:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

So, Greatest Common Divisor of 140, 504, 206, 561 is 1
