Given numbers are 453, 185, 661, 220

The list of prime factors of all numbers are

Prime factors of 453 are 3 x 151

Prime factors of 185 are 5 x 37

Prime factors of 661 are 661

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 453, 185, 661, 220

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

Apply this formula for all numbers.

Step1:

LCM(453, 185) = 83805

GCD(453, 185) = ( 453 x 185 ) / 83805

= 453 / 185

= 453

Step2:

LCM(1, 661) = 661

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

= 1 / 661

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 453, 185, 661, 220 is 1
