Given numbers are 270, 393, 685, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(270, 393) = 35370
GCD(270, 393) = ( 270 x 393 ) / 35370
= 270 / 393
= 270
Step2:
LCM(3, 685) = 2055
GCD(3, 685) = ( 3 x 685 ) / 2055
= 3 / 685
= 3
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 270, 393, 685, 990 is 1
