Given numbers are 385, 891, 217, 425

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(385, 891) = 31185

GCD(385, 891) = ( 385 x 891 ) / 31185

= 385 / 891

= 385

Step2:

LCM(11, 217) = 2387

GCD(11, 217) = ( 11 x 217 ) / 2387

= 11 / 217

= 11

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 385, 891, 217, 425 is 1
