Steps to Calculate GCD of 253, 783, 817, 409 using LCM Formula
Given numbers are 253, 783, 817, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 783) = 198099
GCD(253, 783) = ( 253 x 783 ) / 198099
= 253 / 783
= 253
Step2:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 253, 783, 817, 409 is 1
