Given numbers are 646, 151, 330, 838

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 151 are 151

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 838 are 2 x 419

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

Given numbers are 646, 151, 330, 838

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

Apply this formula for all numbers.

Step1:

LCM(646, 151) = 97546

GCD(646, 151) = ( 646 x 151 ) / 97546

= 646 / 151

= 646

Step2:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 646, 151, 330, 838 is 1
