Given numbers are 385, 140, 576, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 140) = 1540
GCD(385, 140) = ( 385 x 140 ) / 1540
= 385 / 140
= 385
Step2:
LCM(35, 576) = 20160
GCD(35, 576) = ( 35 x 576 ) / 20160
= 35 / 576
= 35
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 385, 140, 576, 278 is 1
