Given numbers are 644, 700, 758, 843

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 758 are 2 x 379

Prime factors of 843 are 3 x 281

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

Given numbers are 644, 700, 758, 843

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

Apply this formula for all numbers.

Step1:

LCM(644, 700) = 16100

GCD(644, 700) = ( 644 x 700 ) / 16100

= 644 / 700

= 644

Step2:

LCM(28, 758) = 10612

GCD(28, 758) = ( 28 x 758 ) / 10612

= 28 / 758

= 28

Step3:

LCM(2, 843) = 1686

GCD(2, 843) = ( 2 x 843 ) / 1686

= 2 / 843

= 2

So, Greatest Common Divisor of 644, 700, 758, 843 is 1
