Given numbers are 646, 688, 385, 850

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 385 are 5 x 7 x 11

Prime factors of 850 are 2 x 5 x 5 x 17

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

Given numbers are 646, 688, 385, 850

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

Apply this formula for all numbers.

Step1:

LCM(646, 688) = 222224

GCD(646, 688) = ( 646 x 688 ) / 222224

= 646 / 688

= 646

Step2:

LCM(2, 385) = 770

GCD(2, 385) = ( 2 x 385 ) / 770

= 2 / 385

= 2

Step3:

LCM(1, 850) = 850

GCD(1, 850) = ( 1 x 850 ) / 850

= 1 / 850

= 1

So, Greatest Common Divisor of 646, 688, 385, 850 is 1
