Steps to Calculate GCD of 289, 821, 35, 809 using LCM Formula
Given numbers are 289, 821, 35, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 821) = 237269
GCD(289, 821) = ( 289 x 821 ) / 237269
= 289 / 821
= 289
Step2:
LCM(1, 35) = 35
GCD(1, 35) = ( 1 x 35 ) / 35
= 1 / 35
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 289, 821, 35, 809 is 1
