Steps to Calculate GCD of 821, 954, 668, 207 using LCM Formula
Given numbers are 821, 954, 668, 207
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 954) = 783234
GCD(821, 954) = ( 821 x 954 ) / 783234
= 821 / 954
= 821
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
So, Greatest Common Divisor of 821, 954, 668, 207 is 1
