Steps to Calculate GCD of 734, 489, 403, 561 using LCM Formula

Given numbers are 734, 489, 403, 561

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

Apply this formula for all numbers.

Step1:

LCM(734, 489) = 358926

GCD(734, 489) = ( 734 x 489 ) / 358926

= 734 / 489

= 734


Step2:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1


Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1


So, Greatest Common Divisor of 734, 489, 403, 561 is 1
