Given numbers are 290, 155, 284, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 155) = 8990
GCD(290, 155) = ( 290 x 155 ) / 8990
= 290 / 155
= 290
Step2:
LCM(5, 284) = 1420
GCD(5, 284) = ( 5 x 284 ) / 1420
= 5 / 284
= 5
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 290, 155, 284, 385 is 1
