Given numbers are 451, 393, 56, 746
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(451, 393) = 177243
GCD(451, 393) = ( 451 x 393 ) / 177243
= 451 / 393
= 451
Step2:
LCM(1, 56) = 56
GCD(1, 56) = ( 1 x 56 ) / 56
= 1 / 56
= 1
Step3:
LCM(1, 746) = 746
GCD(1, 746) = ( 1 x 746 ) / 746
= 1 / 746
= 1
So, Greatest Common Divisor of 451, 393, 56, 746 is 1
