Given numbers are 385, 255, 383, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 255) = 19635
GCD(385, 255) = ( 385 x 255 ) / 19635
= 385 / 255
= 385
Step2:
LCM(5, 383) = 1915
GCD(5, 383) = ( 5 x 383 ) / 1915
= 5 / 383
= 5
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 385, 255, 383, 678 is 1
