Steps to Calculate GCD of 838, 820, 66, 131 using LCM Formula
Given numbers are 838, 820, 66, 131
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 820) = 343580
GCD(838, 820) = ( 838 x 820 ) / 343580
= 838 / 820
= 838
Step2:
LCM(2, 66) = 66
GCD(2, 66) = ( 2 x 66 ) / 66
= 2 / 66
= 2
Step3:
LCM(2, 131) = 262
GCD(2, 131) = ( 2 x 131 ) / 262
= 2 / 131
= 2
So, Greatest Common Divisor of 838, 820, 66, 131 is 1
