Given numbers are 385, 615, 321, 859

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

Apply this formula for all numbers.

Step1:

LCM(385, 615) = 47355

GCD(385, 615) = ( 385 x 615 ) / 47355

= 385 / 615

= 385

Step2:

LCM(5, 321) = 1605

GCD(5, 321) = ( 5 x 321 ) / 1605

= 5 / 321

= 5

Step3:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 385, 615, 321, 859 is 1
