Given numbers are 147, 196, 138, 648

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 196 are 2 x 2 x 7 x 7

Prime factors of 138 are 2 x 3 x 23

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 147, 196, 138, 648

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

Apply this formula for all numbers.

Step1:

LCM(147, 196) = 588

GCD(147, 196) = ( 147 x 196 ) / 588

= 147 / 196

= 147

Step2:

LCM(49, 138) = 6762

GCD(49, 138) = ( 49 x 138 ) / 6762

= 49 / 138

= 49

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 147, 196, 138, 648 is 1
