Given numbers are 454, 387, 973, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 387) = 175698
GCD(454, 387) = ( 454 x 387 ) / 175698
= 454 / 387
= 454
Step2:
LCM(1, 973) = 973
GCD(1, 973) = ( 1 x 973 ) / 973
= 1 / 973
= 1
Step3:
LCM(1, 745) = 745
GCD(1, 745) = ( 1 x 745 ) / 745
= 1 / 745
= 1
So, Greatest Common Divisor of 454, 387, 973, 745 is 1
