Steps to Calculate GCD of 205, 499, 453, 644 using LCM Formula
Given numbers are 205, 499, 453, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 499) = 102295
GCD(205, 499) = ( 205 x 499 ) / 102295
= 205 / 499
= 205
Step2:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 205, 499, 453, 644 is 1
