Given numbers are 437, 416, 145, 643

The list of prime factors of all numbers are

Prime factors of 437 are 19 x 23

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 145 are 5 x 29

Prime factors of 643 are 643

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

Given numbers are 437, 416, 145, 643

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

Apply this formula for all numbers.

Step1:

LCM(437, 416) = 181792

GCD(437, 416) = ( 437 x 416 ) / 181792

= 437 / 416

= 437

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 437, 416, 145, 643 is 1
