Given numbers are 731, 642, 646, 850

The list of prime factors of all numbers are

Prime factors of 731 are 17 x 43

Prime factors of 642 are 2 x 3 x 107

Prime factors of 646 are 2 x 17 x 19

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 731, 642, 646, 850

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

Apply this formula for all numbers.

Step1:

LCM(731, 642) = 469302

GCD(731, 642) = ( 731 x 642 ) / 469302

= 731 / 642

= 731

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 850) = 850

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

= 1 / 850

= 1

So, Greatest Common Divisor of 731, 642, 646, 850 is 1
