Given numbers are 646, 270, 603, 198

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 603 are 3 x 3 x 67

Prime factors of 198 are 2 x 3 x 3 x 11

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

Given numbers are 646, 270, 603, 198

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

Apply this formula for all numbers.

Step1:

LCM(646, 270) = 87210

GCD(646, 270) = ( 646 x 270 ) / 87210

= 646 / 270

= 646

Step2:

LCM(2, 603) = 1206

GCD(2, 603) = ( 2 x 603 ) / 1206

= 2 / 603

= 2

Step3:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

So, Greatest Common Divisor of 646, 270, 603, 198 is 1
