Steps to Calculate GCD of 813, 661, 480, 386 using LCM Formula

Given numbers are 813, 661, 480, 386

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

Apply this formula for all numbers.

Step1:

LCM(813, 661) = 537393

GCD(813, 661) = ( 813 x 661 ) / 537393

= 813 / 661

= 813


Step2:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1


Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1


So, Greatest Common Divisor of 813, 661, 480, 386 is 1
