Given numbers are 406, 761, 828, 145

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 761 are 761

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 145 are 5 x 29

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

Given numbers are 406, 761, 828, 145

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

Apply this formula for all numbers.

Step1:

LCM(406, 761) = 308966

GCD(406, 761) = ( 406 x 761 ) / 308966

= 406 / 761

= 406

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 145) = 145

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

= 1 / 145

= 1

So, Greatest Common Divisor of 406, 761, 828, 145 is 1
