Given numbers are 145, 580, 410, 661

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 410 are 2 x 5 x 41

Prime factors of 661 are 661

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

Given numbers are 145, 580, 410, 661

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

Apply this formula for all numbers.

Step1:

LCM(145, 580) = 580

GCD(145, 580) = ( 145 x 580 ) / 580

= 145 / 580

= 145

Step2:

LCM(145, 410) = 11890

GCD(145, 410) = ( 145 x 410 ) / 11890

= 145 / 410

= 145

Step3:

LCM(5, 661) = 3305

GCD(5, 661) = ( 5 x 661 ) / 3305

= 5 / 661

= 5

So, Greatest Common Divisor of 145, 580, 410, 661 is 1
