Given numbers are 280, 635, 141, 691

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 635 are 5 x 127

Prime factors of 141 are 3 x 47

Prime factors of 691 are 691

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

Given numbers are 280, 635, 141, 691

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

Apply this formula for all numbers.

Step1:

LCM(280, 635) = 35560

GCD(280, 635) = ( 280 x 635 ) / 35560

= 280 / 635

= 280

Step2:

LCM(5, 141) = 705

GCD(5, 141) = ( 5 x 141 ) / 705

= 5 / 141

= 5

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 280, 635, 141, 691 is 1
