Given numbers are 393, 345, 879, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 345) = 45195
GCD(393, 345) = ( 393 x 345 ) / 45195
= 393 / 345
= 393
Step2:
LCM(3, 879) = 879
GCD(3, 879) = ( 3 x 879 ) / 879
= 3 / 879
= 3
Step3:
LCM(3, 221) = 663
GCD(3, 221) = ( 3 x 221 ) / 663
= 3 / 221
= 3
So, Greatest Common Divisor of 393, 345, 879, 221 is 1
