Given numbers are 145, 620, 851, 653

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 851 are 23 x 37

Prime factors of 653 are 653

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

Given numbers are 145, 620, 851, 653

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

Apply this formula for all numbers.

Step1:

LCM(145, 620) = 17980

GCD(145, 620) = ( 145 x 620 ) / 17980

= 145 / 620

= 145

Step2:

LCM(5, 851) = 4255

GCD(5, 851) = ( 5 x 851 ) / 4255

= 5 / 851

= 5

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 145, 620, 851, 653 is 1
