Steps to Calculate GCD of 671, 221, 242, 805 using LCM Formula

Given numbers are 671, 221, 242, 805

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

Apply this formula for all numbers.

Step1:

LCM(671, 221) = 148291

GCD(671, 221) = ( 671 x 221 ) / 148291

= 671 / 221

= 671


Step2:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1


Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1


So, Greatest Common Divisor of 671, 221, 242, 805 is 1
