GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 783) = 11745
GCD(405, 783) = ( 405 x 783 ) / 11745
= 405 / 783
= 405
Step2:
LCM(27, 396) = 1188
GCD(27, 396) = ( 27 x 396 ) / 1188
= 27 / 396
= 27
Step3:
LCM(9, 213) = 639
GCD(9, 213) = ( 9 x 213 ) / 639
= 9 / 213
= 9
So, Greatest Common Divisor of 405, 783, 396, 213 is 3
