Steps to Calculate GCD of 785, 971, 389, 309 using LCM Formula
Given numbers are 785, 971, 389, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 971) = 762235
GCD(785, 971) = ( 785 x 971 ) / 762235
= 785 / 971
= 785
Step2:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 785, 971, 389, 309 is 1
