Given numbers are 644, 324, 313, 505
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 324) = 52164
GCD(644, 324) = ( 644 x 324 ) / 52164
= 644 / 324
= 644
Step2:
LCM(4, 313) = 1252
GCD(4, 313) = ( 4 x 313 ) / 1252
= 4 / 313
= 4
Step3:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
So, Greatest Common Divisor of 644, 324, 313, 505 is 1
