GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 270) = 810
GCD(405, 270) = ( 405 x 270 ) / 810
= 405 / 270
= 405
Step2:
LCM(135, 160) = 4320
GCD(135, 160) = ( 135 x 160 ) / 4320
= 135 / 160
= 135
Step3:
LCM(5, 555) = 555
GCD(5, 555) = ( 5 x 555 ) / 555
= 5 / 555
= 5
So, Greatest Common Divisor of 405, 270, 160, 555 is 5
