Given numbers are 678, 622, 424, 147

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

Apply this formula for all numbers.

Step1:

LCM(678, 622) = 210858

GCD(678, 622) = ( 678 x 622 ) / 210858

= 678 / 622

= 678

Step2:

LCM(2, 424) = 424

GCD(2, 424) = ( 2 x 424 ) / 424

= 2 / 424

= 2

Step3:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

So, Greatest Common Divisor of 678, 622, 424, 147 is 1
