Given numbers are 215, 154, 546, 427

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 154 are 2 x 7 x 11

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 427 are 7 x 61

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

Given numbers are 215, 154, 546, 427

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

Apply this formula for all numbers.

Step1:

LCM(215, 154) = 33110

GCD(215, 154) = ( 215 x 154 ) / 33110

= 215 / 154

= 215

Step2:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 215, 154, 546, 427 is 1
