Given numbers are 668, 923, 534, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 923) = 616564
GCD(668, 923) = ( 668 x 923 ) / 616564
= 668 / 923
= 668
Step2:
LCM(1, 534) = 534
GCD(1, 534) = ( 1 x 534 ) / 534
= 1 / 534
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 668, 923, 534, 420 is 1
