Given numbers are 140, 729, 451, 505

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 729 are 3 x 3 x 3 x 3 x 3 x 3

Prime factors of 451 are 11 x 41

Prime factors of 505 are 5 x 101

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

Given numbers are 140, 729, 451, 505

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

Apply this formula for all numbers.

Step1:

LCM(140, 729) = 102060

GCD(140, 729) = ( 140 x 729 ) / 102060

= 140 / 729

= 140

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 140, 729, 451, 505 is 1
