Given numbers are 402, 972, 504, 781

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 781 are 11 x 71

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

Given numbers are 402, 972, 504, 781

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

Apply this formula for all numbers.

Step1:

LCM(402, 972) = 65124

GCD(402, 972) = ( 402 x 972 ) / 65124

= 402 / 972

= 402

Step2:

LCM(6, 504) = 504

GCD(6, 504) = ( 6 x 504 ) / 504

= 6 / 504

= 6

Step3:

LCM(6, 781) = 4686

GCD(6, 781) = ( 6 x 781 ) / 4686

= 6 / 781

= 6

So, Greatest Common Divisor of 402, 972, 504, 781 is 1
