Given numbers are 133, 686, 381, 402

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 381 are 3 x 127

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 133, 686, 381, 402

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

Apply this formula for all numbers.

Step1:

LCM(133, 686) = 13034

GCD(133, 686) = ( 133 x 686 ) / 13034

= 133 / 686

= 133

Step2:

LCM(7, 381) = 2667

GCD(7, 381) = ( 7 x 381 ) / 2667

= 7 / 381

= 7

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 133, 686, 381, 402 is 1
