Steps to Calculate GCD of 669, 647, 63, 443 using LCM Formula
Given numbers are 669, 647, 63, 443
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 647) = 432843
GCD(669, 647) = ( 669 x 647 ) / 432843
= 669 / 647
= 669
Step2:
LCM(1, 63) = 63
GCD(1, 63) = ( 1 x 63 ) / 63
= 1 / 63
= 1
Step3:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
So, Greatest Common Divisor of 669, 647, 63, 443 is 1
