Steps to Calculate GCD of 393, 739, 21, 249 using LCM Formula
Given numbers are 393, 739, 21, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 739) = 290427
GCD(393, 739) = ( 393 x 739 ) / 290427
= 393 / 739
= 393
Step2:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 393, 739, 21, 249 is 1
