Given numbers are 820, 728, 369, 127

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 369 are 3 x 3 x 41

Prime factors of 127 are 127

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

Given numbers are 820, 728, 369, 127

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

Apply this formula for all numbers.

Step1:

LCM(820, 728) = 149240

GCD(820, 728) = ( 820 x 728 ) / 149240

= 820 / 728

= 820

Step2:

LCM(4, 369) = 1476

GCD(4, 369) = ( 4 x 369 ) / 1476

= 4 / 369

= 4

Step3:

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

= 1 / 127

= 1

So, Greatest Common Divisor of 820, 728, 369, 127 is 1
