Given numbers are 126, 153, 235, 221

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 153 are 3 x 3 x 17

Prime factors of 235 are 5 x 47

Prime factors of 221 are 13 x 17

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

Given numbers are 126, 153, 235, 221

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

Apply this formula for all numbers.

Step1:

LCM(126, 153) = 2142

GCD(126, 153) = ( 126 x 153 ) / 2142

= 126 / 153

= 126

Step2:

LCM(9, 235) = 2115

GCD(9, 235) = ( 9 x 235 ) / 2115

= 9 / 235

= 9

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 126, 153, 235, 221 is 1
