Given numbers are 287, 813, 312, 413
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 813) = 233331
GCD(287, 813) = ( 287 x 813 ) / 233331
= 287 / 813
= 287
Step2:
LCM(1, 312) = 312
GCD(1, 312) = ( 1 x 312 ) / 312
= 1 / 312
= 1
Step3:
LCM(1, 413) = 413
GCD(1, 413) = ( 1 x 413 ) / 413
= 1 / 413
= 1
So, Greatest Common Divisor of 287, 813, 312, 413 is 1
