Given numbers are 387, 703, 280, 210

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 703 are 19 x 37

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 210 are 2 x 3 x 5 x 7

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

Given numbers are 387, 703, 280, 210

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

Apply this formula for all numbers.

Step1:

LCM(387, 703) = 272061

GCD(387, 703) = ( 387 x 703 ) / 272061

= 387 / 703

= 387

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 387, 703, 280, 210 is 1
