Given numbers are 660, 923, 645, 741
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 923) = 609180
GCD(660, 923) = ( 660 x 923 ) / 609180
= 660 / 923
= 660
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 741) = 741
GCD(1, 741) = ( 1 x 741 ) / 741
= 1 / 741
= 1
So, Greatest Common Divisor of 660, 923, 645, 741 is 1
