Given numbers are 215, 677, 511, 420

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 677 are 677

Prime factors of 511 are 7 x 73

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 215, 677, 511, 420

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

Apply this formula for all numbers.

Step1:

LCM(215, 677) = 145555

GCD(215, 677) = ( 215 x 677 ) / 145555

= 215 / 677

= 215

Step2:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 215, 677, 511, 420 is 1
