Given numbers are 668, 447, 518, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 447) = 298596
GCD(668, 447) = ( 668 x 447 ) / 298596
= 668 / 447
= 668
Step2:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 668, 447, 518, 445 is 1
