Given numbers are 287, 468, 394, 860
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 468) = 134316
GCD(287, 468) = ( 287 x 468 ) / 134316
= 287 / 468
= 287
Step2:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
Step3:
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
= 1 / 860
= 1
So, Greatest Common Divisor of 287, 468, 394, 860 is 1
