Given numbers are 668, 420, 147, 567

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

Apply this formula for all numbers.

Step1:

LCM(668, 420) = 70140

GCD(668, 420) = ( 668 x 420 ) / 70140

= 668 / 420

= 668

Step2:

LCM(4, 147) = 588

GCD(4, 147) = ( 4 x 147 ) / 588

= 4 / 147

= 4

Step3:

LCM(1, 567) = 567

GCD(1, 567) = ( 1 x 567 ) / 567

= 1 / 567

= 1

So, Greatest Common Divisor of 668, 420, 147, 567 is 1
