Given numbers are 434, 771, 800, 490

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 771 are 3 x 257

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 434, 771, 800, 490

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

Apply this formula for all numbers.

Step1:

LCM(434, 771) = 334614

GCD(434, 771) = ( 434 x 771 ) / 334614

= 434 / 771

= 434

Step2:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 434, 771, 800, 490 is 1
