Given numbers are 644, 712, 470, 219

The list of prime factors of all numbers are

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

Prime factors of 712 are 2 x 2 x 2 x 89

Prime factors of 470 are 2 x 5 x 47

Prime factors of 219 are 3 x 73

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

Given numbers are 644, 712, 470, 219

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

Apply this formula for all numbers.

Step1:

LCM(644, 712) = 114632

GCD(644, 712) = ( 644 x 712 ) / 114632

= 644 / 712

= 644

Step2:

LCM(4, 470) = 940

GCD(4, 470) = ( 4 x 470 ) / 940

= 4 / 470

= 4

Step3:

LCM(2, 219) = 438

GCD(2, 219) = ( 2 x 219 ) / 438

= 2 / 219

= 2

So, Greatest Common Divisor of 644, 712, 470, 219 is 1
