Given numbers are 891, 221, 415, 354

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

Apply this formula for all numbers.

Step1:

LCM(891, 221) = 196911

GCD(891, 221) = ( 891 x 221 ) / 196911

= 891 / 221

= 891

Step2:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

Step3:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

So, Greatest Common Divisor of 891, 221, 415, 354 is 1
