Given numbers are 666, 323, 213, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 323) = 215118
GCD(666, 323) = ( 666 x 323 ) / 215118
= 666 / 323
= 666
Step2:
LCM(1, 213) = 213
GCD(1, 213) = ( 1 x 213 ) / 213
= 1 / 213
= 1
Step3:
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
= 1 / 811
= 1
So, Greatest Common Divisor of 666, 323, 213, 811 is 1
