Given numbers are 387, 789, 141, 980

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 789 are 3 x 263

Prime factors of 141 are 3 x 47

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 387, 789, 141, 980

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

Apply this formula for all numbers.

Step1:

LCM(387, 789) = 101781

GCD(387, 789) = ( 387 x 789 ) / 101781

= 387 / 789

= 387

Step2:

LCM(3, 141) = 141

GCD(3, 141) = ( 3 x 141 ) / 141

= 3 / 141

= 3

Step3:

LCM(3, 980) = 2940

GCD(3, 980) = ( 3 x 980 ) / 2940

= 3 / 980

= 3

So, Greatest Common Divisor of 387, 789, 141, 980 is 1
