Steps to Calculate GCD of 221, 185, 437, 251 using LCM Formula

Given numbers are 221, 185, 437, 251

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

Apply this formula for all numbers.

Step1:

LCM(221, 185) = 40885

GCD(221, 185) = ( 221 x 185 ) / 40885

= 221 / 185

= 221


Step2:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1


Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1


So, Greatest Common Divisor of 221, 185, 437, 251 is 1
