Given numbers are 660, 453, 408, 769
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 453) = 99660
GCD(660, 453) = ( 660 x 453 ) / 99660
= 660 / 453
= 660
Step2:
LCM(3, 408) = 408
GCD(3, 408) = ( 3 x 408 ) / 408
= 3 / 408
= 3
Step3:
LCM(3, 769) = 2307
GCD(3, 769) = ( 3 x 769 ) / 2307
= 3 / 769
= 3
So, Greatest Common Divisor of 660, 453, 408, 769 is 1
