Given numbers are 400, 451, 843, 661

The list of prime factors of all numbers are

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

Prime factors of 451 are 11 x 41

Prime factors of 843 are 3 x 281

Prime factors of 661 are 661

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

Given numbers are 400, 451, 843, 661

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

Apply this formula for all numbers.

Step1:

LCM(400, 451) = 180400

GCD(400, 451) = ( 400 x 451 ) / 180400

= 400 / 451

= 400

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

Step3:

LCM(1, 661) = 661

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

= 1 / 661

= 1

So, Greatest Common Divisor of 400, 451, 843, 661 is 1
