Given numbers are 290, 385, 433, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 385) = 22330
GCD(290, 385) = ( 290 x 385 ) / 22330
= 290 / 385
= 290
Step2:
LCM(5, 433) = 2165
GCD(5, 433) = ( 5 x 433 ) / 2165
= 5 / 433
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 290, 385, 433, 644 is 1
