Given numbers are 553, 214, 663, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(553, 214) = 118342
GCD(553, 214) = ( 553 x 214 ) / 118342
= 553 / 214
= 553
Step2:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 553, 214, 663, 217 is 1
