Given numbers are 666, 213, 421, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 213) = 47286
GCD(666, 213) = ( 666 x 213 ) / 47286
= 666 / 213
= 666
Step2:
LCM(3, 421) = 1263
GCD(3, 421) = ( 3 x 421 ) / 1263
= 3 / 421
= 3
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 666, 213, 421, 865 is 1
