Given numbers are 624, 668, 256, 688

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

Apply this formula for all numbers.

Step1:

LCM(624, 668) = 104208

GCD(624, 668) = ( 624 x 668 ) / 104208

= 624 / 668

= 624

Step2:

LCM(4, 256) = 256

GCD(4, 256) = ( 4 x 256 ) / 256

= 4 / 256

= 4

Step3:

LCM(4, 688) = 688

GCD(4, 688) = ( 4 x 688 ) / 688

= 4 / 688

= 4

So, Greatest Common Divisor of 624, 668, 256, 688 is 4
