Steps to Calculate GCD of 408, 653, 761, 305 using LCM Formula
Given numbers are 408, 653, 761, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 653) = 266424
GCD(408, 653) = ( 408 x 653 ) / 266424
= 408 / 653
= 408
Step2:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 408, 653, 761, 305 is 1
