Given numbers are 407, 745, 116, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 745) = 303215
GCD(407, 745) = ( 407 x 745 ) / 303215
= 407 / 745
= 407
Step2:
LCM(1, 116) = 116
GCD(1, 116) = ( 1 x 116 ) / 116
= 1 / 116
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 407, 745, 116, 645 is 1
