Steps to Calculate GCD of 489, 253, 25, 435 using LCM Formula
Given numbers are 489, 253, 25, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 253) = 123717
GCD(489, 253) = ( 489 x 253 ) / 123717
= 489 / 253
= 489
Step2:
LCM(1, 25) = 25
GCD(1, 25) = ( 1 x 25 ) / 25
= 1 / 25
= 1
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 489, 253, 25, 435 is 1
