Steps to Calculate GCD of 309, 679, 530, 889 using LCM Formula

Given numbers are 309, 679, 530, 889

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

Apply this formula for all numbers.

Step1:

LCM(309, 679) = 209811

GCD(309, 679) = ( 309 x 679 ) / 209811

= 309 / 679

= 309


Step2:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1


Step3:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1


So, Greatest Common Divisor of 309, 679, 530, 889 is 1
