Steps to Calculate GCD of 428, 673, 164, 245 using LCM Formula
Given numbers are 428, 673, 164, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 673) = 288044
GCD(428, 673) = ( 428 x 673 ) / 288044
= 428 / 673
= 428
Step2:
LCM(1, 164) = 164
GCD(1, 164) = ( 1 x 164 ) / 164
= 1 / 164
= 1
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 428, 673, 164, 245 is 1
