Given numbers are 280, 641, 400, 661

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 641 are 641

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 661 are 661

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

Given numbers are 280, 641, 400, 661

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

Apply this formula for all numbers.

Step1:

LCM(280, 641) = 179480

GCD(280, 641) = ( 280 x 641 ) / 179480

= 280 / 641

= 280

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 280, 641, 400, 661 is 1
