Steps to Calculate GCD of 405, 451, 681, 194 using LCM Formula

Given numbers are 405, 451, 681, 194

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

Apply this formula for all numbers.

Step1:

LCM(405, 451) = 182655

GCD(405, 451) = ( 405 x 451 ) / 182655

= 405 / 451

= 405


Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1


Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1


So, Greatest Common Divisor of 405, 451, 681, 194 is 1
