Given numbers are 145, 746, 644, 461

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 746 are 2 x 373

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 461 are 461

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

Given numbers are 145, 746, 644, 461

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

Apply this formula for all numbers.

Step1:

LCM(145, 746) = 108170

GCD(145, 746) = ( 145 x 746 ) / 108170

= 145 / 746

= 145

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

= 1 / 461

= 1

So, Greatest Common Divisor of 145, 746, 644, 461 is 1
