Steps to Calculate GCD of 340, 196, 21, 503 using LCM Formula
Given numbers are 340, 196, 21, 503
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 196) = 16660
GCD(340, 196) = ( 340 x 196 ) / 16660
= 340 / 196
= 340
Step2:
LCM(4, 21) = 84
GCD(4, 21) = ( 4 x 21 ) / 84
= 4 / 21
= 4
Step3:
LCM(1, 503) = 503
GCD(1, 503) = ( 1 x 503 ) / 503
= 1 / 503
= 1
So, Greatest Common Divisor of 340, 196, 21, 503 is 1
