Given numbers are 861, 212, 792, 434

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 212 are 2 x 2 x 53

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 861, 212, 792, 434

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

Apply this formula for all numbers.

Step1:

LCM(861, 212) = 182532

GCD(861, 212) = ( 861 x 212 ) / 182532

= 861 / 212

= 861

Step2:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 861, 212, 792, 434 is 1
