Given numbers are 402, 716, 390, 981

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 716 are 2 x 2 x 179

Prime factors of 390 are 2 x 3 x 5 x 13

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 402, 716, 390, 981

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

Apply this formula for all numbers.

Step1:

LCM(402, 716) = 143916

GCD(402, 716) = ( 402 x 716 ) / 143916

= 402 / 716

= 402

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 981) = 1962

GCD(2, 981) = ( 2 x 981 ) / 1962

= 2 / 981

= 2

So, Greatest Common Divisor of 402, 716, 390, 981 is 1
