Given numbers are 678, 555, 668, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 555) = 125430
GCD(678, 555) = ( 678 x 555 ) / 125430
= 678 / 555
= 678
Step2:
LCM(3, 668) = 2004
GCD(3, 668) = ( 3 x 668 ) / 2004
= 3 / 668
= 3
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 678, 555, 668, 447 is 1
