Given numbers are 219, 477, 153, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(219, 477) = 34821
GCD(219, 477) = ( 219 x 477 ) / 34821
= 219 / 477
= 219
Step2:
LCM(3, 153) = 153
GCD(3, 153) = ( 3 x 153 ) / 153
= 3 / 153
= 3
Step3:
LCM(3, 668) = 2004
GCD(3, 668) = ( 3 x 668 ) / 2004
= 3 / 668
= 3
So, Greatest Common Divisor of 219, 477, 153, 668 is 1
