Given numbers are 145, 456, 580, 851

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Prime factors of 851 are 23 x 37

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

Given numbers are 145, 456, 580, 851

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

Apply this formula for all numbers.

Step1:

LCM(145, 456) = 66120

GCD(145, 456) = ( 145 x 456 ) / 66120

= 145 / 456

= 145

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 145, 456, 580, 851 is 1
