Given numbers are 386, 648, 147, 981

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

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

Prime factors of 147 are 3 x 7 x 7

Prime factors of 981 are 3 x 3 x 109

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

Given numbers are 386, 648, 147, 981

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

Apply this formula for all numbers.

Step1:

LCM(386, 648) = 125064

GCD(386, 648) = ( 386 x 648 ) / 125064

= 386 / 648

= 386

Step2:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 386, 648, 147, 981 is 1
