Given numbers are 215, 395, 891, 741

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

Apply this formula for all numbers.

Step1:

LCM(215, 395) = 16985

GCD(215, 395) = ( 215 x 395 ) / 16985

= 215 / 395

= 215

Step2:

LCM(5, 891) = 4455

GCD(5, 891) = ( 5 x 891 ) / 4455

= 5 / 891

= 5

Step3:

LCM(1, 741) = 741

GCD(1, 741) = ( 1 x 741 ) / 741

= 1 / 741

= 1

So, Greatest Common Divisor of 215, 395, 891, 741 is 1
