Given numbers are 287, 686, 766, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 686) = 28126
GCD(287, 686) = ( 287 x 686 ) / 28126
= 287 / 686
= 287
Step2:
LCM(7, 766) = 5362
GCD(7, 766) = ( 7 x 766 ) / 5362
= 7 / 766
= 7
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 287, 686, 766, 393 is 1
