Given numbers are 402, 671, 945, 851

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 671 are 11 x 61

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 851 are 23 x 37

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

Given numbers are 402, 671, 945, 851

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

Apply this formula for all numbers.

Step1:

LCM(402, 671) = 269742

GCD(402, 671) = ( 402 x 671 ) / 269742

= 402 / 671

= 402

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 402, 671, 945, 851 is 1
