Given numbers are 445, 215, 108, 578
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 215) = 19135
GCD(445, 215) = ( 445 x 215 ) / 19135
= 445 / 215
= 445
Step2:
LCM(5, 108) = 540
GCD(5, 108) = ( 5 x 108 ) / 540
= 5 / 108
= 5
Step3:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
So, Greatest Common Divisor of 445, 215, 108, 578 is 1
