Steps to Calculate GCD of 309, 397, 283, 777 using LCM Formula

Given numbers are 309, 397, 283, 777

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

Apply this formula for all numbers.

Step1:

LCM(309, 397) = 122673

GCD(309, 397) = ( 309 x 397 ) / 122673

= 309 / 397

= 309


Step2:

LCM(1, 283) = 283

GCD(1, 283) = ( 1 x 283 ) / 283

= 1 / 283

= 1


Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1
