Given numbers are 644, 568, 704, 123

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

Apply this formula for all numbers.

Step1:

LCM(644, 568) = 91448

GCD(644, 568) = ( 644 x 568 ) / 91448

= 644 / 568

= 644

Step2:

LCM(4, 704) = 704

GCD(4, 704) = ( 4 x 704 ) / 704

= 4 / 704

= 4

Step3:

LCM(4, 123) = 492

GCD(4, 123) = ( 4 x 123 ) / 492

= 4 / 123

= 4

So, Greatest Common Divisor of 644, 568, 704, 123 is 1
