Given numbers are 385, 756, 243, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 756) = 41580
GCD(385, 756) = ( 385 x 756 ) / 41580
= 385 / 756
= 385
Step2:
LCM(7, 243) = 1701
GCD(7, 243) = ( 7 x 243 ) / 1701
= 7 / 243
= 7
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 385, 756, 243, 435 is 1
