Given numbers are 168, 290, 43, 678

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

Apply this formula for all numbers.

Step1:

LCM(168, 290) = 24360

GCD(168, 290) = ( 168 x 290 ) / 24360

= 168 / 290

= 168

Step2:

LCM(2, 43) = 86

GCD(2, 43) = ( 2 x 43 ) / 86

= 2 / 43

= 2

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 168, 290, 43, 678 is 1
